The image of Aishwarya Rai in a striking yellow sari with lots of gold jewellery walking the red carpet at Cannes 2002 is one that a generation of Indian movie fans may not forget.

Few Indians were familiar with Cannes until the actress made an appearance on the French Riviera. Not only did Rai introduce fans back home to the world’s leading cinema showcase, she also made global audiences take note of Bollywood. This year, the 66th Cannes festival is showcasing India as a guest country to mark the centenary of its film industry.

Celebrities such as Sonam Kapoor, Mallika Sherawat, Nawazuddin Siddiqui, Frieda Pinto and Amitabh Bachchan made an appearance – and had to step up their fashion game.

Glamour is key at the annual film festival and the trek down the red carpet is fraught with risk for the glitterati.
