LOS ANGELES: Actor Gary Oldman, who starred in the recent blockbuster Batman movies let it slip that a new flick about the crime-fighting superhero is set to start filming next year — but you didn’t hear it from him.

Oldman, who played Commissioner Gordon in director Christopher Nolan’s Batman Begins and The Dark Knight, was promoting another movie, thriller The Book of Eli, at the giant Comic-Con convention in San Diego when he was asked about plans for a third movie in Nolan’s hit series.

“We start filming the next Batman next year, which means it won’t come out for another two years,” he said, before adding in a sly tone, “but you didn’t hear that from me.”

No details of a third Nolan Batman flick have ever been announced and a Warner Bros spokeswoman declined to comment, which only added mystery to intrigue.
