The studio behind Batman movie “The Dark Knight” has set Jan. 23 as the date for the movie’s re-release in IMAX and conventional theaters.

Studios often re-release movies in the lead-up to the Oscars, and “The Dark Knight” has been talked about for a number of trophies.

The biggest buzz surrounds the late Heath Ledger, who played Batman’s Machiavellian arch enemy The Joker and died last year of an overdose of prescription drugs. His performance already won him a posthumous Golden Globe award for best supporting actor, and Ledger could get an Oscar nomination as well.

Industry watchers expect the re-release of “The Dark Knight” to push the film past the $1 billion mark in worldwide box office sales. The film is already the second-highest grossing movie behind the 1997 film “Titanic.”

“The Dark Knight” will play in 255 theaters in the U.S. and Canada, including 142 IMAX theaters, said studio Warner Bros. The movie will play in about 32 IMAX locations internationally, the studio said.

Segments of the film were shot in IMAX, a giant screen format that Hollywood has increasingly turned to in recent years. “The Dark Knight” last year made more than $48 million in U.S. and Canada box office sales from IMAX showings.
