The science fiction film, set in South Africa, is an allegory on segregation and xenophobia, with alien life forms cooped up in a township of the type that grew up under apartheid and victimised and despised by humans of all descriptions.

No section of human society comes across particularly well, but the Nigerians are crudely caricatured as gangsters, cannibals, pimps, prostitutes and dealers in guns and addictive drugs (in this case cat food). The gang leader’s name sounds exactly like the surname of Nigeria’s former President Olusegun Obasanjo.

It’s just a film of course and the slurs needn’t overly detract from the entertainment. (They didn’t for the Nigerian half of my family anyway).

But this does raise a question as to why Nigerians should be seen as fair targets and casually turned into comic book gangsters? Would the film makers have got away with showing other nations or groups in this way? Would they have feared the backlash?

It also raises the question as to what Nigeria can do about really changing its image – beyond rebranding and advertising campaigns.

It could be argued that the immense and undoubted talent of law-abiding Nigerians, the vast majority at home and abroad, does not get the recognition it deserves in the rest of the world despite the acclaim for the greatest Nigerian writers, musicians, footballers and athletes.  Nor may the sacrifice of Nigerians who have given their lives as peacekeepers in Africa and elsewhere.

But we can’t forget that there are still plenty of Nigeria’s 150 million people who have no qualms about giving their country a bad name.

What about the Nigerians imprisoned in Asia and Europe for smuggling drugs? The ‘419’ fraudsters with their email appeals? The kidnappers and oil thieves of the Niger delta? Those politicians who rig elections with fraud, intimidation and bribery? Those officials who see their positions merely as a chance to fill their boots and may be all too ready to subvert the courts or obstruct people struggling to do business fairly?

And how can Nigeria’s image improve while it cannot regularly light up the homes of its people - despite enormous energy resources and billions of dollars spent?

Does Nigeria suffer unfairly from an image problem or will it improve its image once it deals with its problems?

The list cuts across the business elite and Nigeria's regions and also includes many politically powerful figures. (And it doesn't even appear that all those who could have been named as directors of the debtor companies have been identified).

It raises a question as to whether so many of the great and good are simply unable to pay their debts and if so what that means for business in Nigeria as a whole? If they could pay up, then why haven't they?

It also raises a question as to how those 'named and shamed' will react, particularly those with major political sway, in a country where behind the scenes manipulation is a way of life.

The Economic and Financial Crimes Commission has set a deadline for the debtors to start coming up with money or face arrest, but its efforts to prosecute former state governors in the past were sometimes stymied and its former boss Nuhu Ribadu driven from office.

"You have the power to hold your leaders accountable, and to build institutions that serve the people. You can serve in your communities, and harness your energy and education to create new wealth and build new connections to the world. You can conquer disease, end conflicts, and make change from the bottom up. You can do that. Yes you can. Because in this moment, history is on the move,” Obama said.

"Freedom is your inheritance. Now, it is your responsibility to build upon freedom's foundation. And if you do, we will look back years from now to places like Accra and say that this was the time when the promise was realized -- this was the moment when prosperity was forged; pain was overcome; and a new era of progress began. This can be the time when we witness the triumph of justice once more."

To listen to the whole speech, you can find a link on the White House website.

As Obama put it: "Make no mistake: history is on the side of these brave Africans, and not with those who use coups or change constitutions to stay in power. Africa doesn't need strongmen, it needs strong institutions.”

There was no doubt they were strong words from the son of a Kenyan immigrant, who through elections has become the leader of the world’s most powerful country. Obama’s background may also give his message a better chance of being heard than those of past American leaders lecturing Africa on what it needs to do.

But when all is said and done and Obama flies off to deal with more urgent U.S. priorities, will the message be heeded? Will Africa live up to that promise?

The cocaine cartels that used West Africa, and Guinea-Bissau in particular, as a conduit to Europe were long accused of worsening the chaos in one of the region’s poorest and most troubled states by buying off some factions of the security forces and political leaders.

But if so, things may have gone too far.

In less than a year, Guinea-Bissau has lost President Joao Bernardo “Nino” Vieira (dead), the head of the army (dead), the head of the navy (fled), a former defence minister (dead) and a candidate to replace the slain president in the June 28 election (dead). And those are just some of the figures at the top.

Whichever of Guinea-Bissau’s leaders might have been involved in the drugs trade and which were trying to fight it, the removal of such a swathe of the leadership appears for now at least to have knocked the traffickers off balance too.

Drug smuggling through West Africa has plummeted, according to the U.N., despite the fact that its geography also makes it an ideal bridge between Latin America and Europe.

"The fact that big traffickers do not any longer have certain partners in power clearly have disrupted the routes," said Antonio Mazzitelli, regional head of the United Nations Office on Drugs and Crime. "A trafficker would never bring 2 tonnes of drugs to a country where he is not sure he can operate,” he told Reuters.

Political changes in Guinea, where a junta seized power after the death of President Lansana Conte, and Ghana, where the opposition won a democratic election, also appear to have limited their use as smuggling conduits for now.

An election in Guinea-Bissau now offers a chance for a new start. With greater international support its chance of becoming a failed state could have improved.

A question for the West African countries – and for the drug traffickers – may be whether administrations that become more entrenched over time will more easily fall prey to the lure of the drug money despite the dangers.

But while Western countries may show willing when it comes to emergency aid, they are still reluctant to give money to the government between President Robert Mugabe and Prime Minister Morgan Tsvangirai, his old rival.

First, they say, there must be broader political reforms and a clearer demonstration of respect for human rights.

The Western countries have long been at odds with Mugabe, accusing him of ruining Zimbabwe after the seizure of white-owned farms, of widespread human rights abuses and of making a mockery of elections last year that were widely condemned outside Zimbabwe.

But if those countries don’t come up with the finance that the government needs, some believe there is a danger it could undermine prospects for change rather than strengthening them.

"My advice is for the international community to engage Zimbabwe as the opposite of this will only benefit hardliners," Tsvangirai told a visiting French minister last week.

The unity government has said it won more than $1 billion in promised credit lines from African banks for private firms, but says it needs more than $8 billion for reconstruction.

Should Western countries aid the government now, or is it too soon?

You can have your say on the survey below. Your comments are welcome too.

“The new President of the Republic will be a president for all, and he will work to unite the country around a programme of action that will see an improvement in the delivery of services,” Zuma said after the African National Congress won its sweeping victory.

“We may disagree on how to bring about a better life for all, but what unites us is the fact that this country belongs to all of us, black, white, coloured and Indian equally. We will need to work together on issues that are in the national interest, on which there is no need to compete or permanently bicker.”

Despite the strongest opposition challenge since the end of apartheid, the slick ANC campaign delivered the vote and persuaded a majority of South Africans that the party that has ruled since 1994 could also be the one to deliver change – more action against poverty, crime, AIDS and other concerns.

But unity is always going to be tough in a country with as many divisions as South Africa. The formerly monolithic ANC itself split last year after it ousted former President Thabo Mbeki.

The vote clearly showed up the racial divide 15 years after the end of rule by the white minority.

The vast majority of black Africans had clearly voted for the ANC, whose credentials are still strong for ending apartheid. The voters included those in KwaZulu Natal province, where the Inkatha Freedom Party used to be dominant. Zuma, a son of the soil, definitely helped the party win more votes there.

Coloured and white minorities, however, opted heavily for the opposition Democratic Alliance, which won convincingly in the Western Cape province, where they make up the biggest proportion of the population. Led by Helen Zille, a white woman, the Democratic Alliance has had little success winning over black African voters.

Zuma made great efforts to charm South Africans of all colours before the election, making a particular effort to woo Afrikaners. He also appeared to want to make it more of a priority than Mbeki.

But South Africa’s communities still live their lives very much apart, even if the emergence of a growing black middle class means the divisions along wealth lines no longer correlate as precisely with race as they once did.

When he takes office, Zuma will face demands from all sides – from those who want a greater share of the wealth and more opportunities and from those who feel they are politically marginalised. What could Zuma do to unite South Africa? Can he succeed? Does unity really matter for South Africa anyway?

So far, the results don’t look too different from the pre-poll forecasts. An ANC victory was never in doubt and the battle was as much as anything about whether the party could keep its two-thirds majority in parliament, which lets it change the constitution and further entrench its power. That was still in doubt after early figures.

There was not much good news for the Congress of the People (COPE), formed by loyalists of ousted former President Thabo Mbeki. With only about eight percent of the vote so far, the question may be as much whether it survives as whether it can supplant the Democratic Alliance as the main opposition.

The DA seemed to have done fairly well with its “Stop Zuma” campaign, at least in its Western Cape stronghold, but there was no sign of it making inroads among the black majority.

Whatever losses the ANC had made to COPE and the DA, it seemed to have made some of them up in KwaZulu-Natal, Zuma’s Zulu heartland, where it battered the once locally dominant Inkatha Freedom Party.

It certainly looks as though Zuma’s support was not affected by the fact the corruption charges against him were dismissed on a technicality rather than after a trial.

How well placed will he now be to deliver the change that many South Africans say they want on fighting crime, poverty, corruption and AIDS? Will COPE survive or might its supporters start to drift back to the ANC? Will the opposition ever really be able to challenge the ANC?

Are you celebrating or disappointed? We want to hear from you.

Central Bank Governor Gideon Gono said the central bank took foreign currency from private accounts to help pay for some $2 billion in loans to state-owned companies and utilities and for power and grain imports. He said the government still had to repay about $1.2 billion, so the bank could repay the money it owes.

Heading the central bank at a time Zimbabwe was suffering economic collapse and hyperinflation that touched at least 231 million percent a year (according to official figures) was never going to be a badge of honour for the governor, but as he made clear in his statement, Zimbabwe’s problems went beyond economics.

"It was a political problem and not an economic one that drove us into the difficulties this nation experienced, and quasi-fiscal operations were a response to those political challenges we have now resolved through the inclusive government," the statement said. "Our call is to let bygones be bygones and for everyone and every entity to start anew and open a new page."

Gono has come under pressure from Prime Minister Morgan Tsvangirai's Movement for Democratic Change (MDC) to resign since the former opposition party joined Mugabe in a unity government in February. Western diplomats have also said Gono’s departure could help bring a resumption of badly needed aid.

Are his days numbered now Tsvangirai and Mugabe seem to be working together more closely than many might have expected?

So how did Africa fare?

On the face of things, perhaps not too badly.

“Our global plan for recovery must have at its heart the needs and jobs of hard-working families, not just in developed countries but in emerging markets and the poorest countries of the world too,” the communique says in paragraph 3.

In concrete terms:

• Resources available to the IMF will be trebled to $750 billion.
•  There will be support for a new allocation of Special Drawing Rights of $250 billion – something that could help poor countries
• There will be support for $100 billion more lending by Multilateral Development Banks (those include the World Bank Group and the African Development Bank)
• There will be $250 billion support for trade finance.
• Use will be made of resources from IMF gold sales “for concessional finance for the poorest countries”.
• Global financial institutions will be strengthened and reformed, ensuring that emerging and developing economies, including the poorest, must have greater voice and representation.”

The point on the gold sales was something for which Africa, represented at the summit by Ethiopian Prime Minister Meles Zenawi, had made a particular push.

But not all appeared so impressed. In East Africa based Business Daily, Allan Odhiambo’s piece was headlined “Africa thrown to back burner at G20 meeting.”

According to Nigeria’s ThisDay newspaper, President Umaru Yar’Adua’s main lament was the fact that Africa’s most populous country was not there (South Africa, with the continent’s biggest economy, was represented).

South Africa’s President Kgalema Motlanthe was quoted as saying he was “quite pleased” with the results of the summit.

How well do you think the G20 did for Africa? Will Africa really have a bigger say over the global financial system in future? Will that help?
