The actor has been approached by the film's director Chris Nolan for a lead role in the latest instalment about the caped crusader and although insiders are keeping his part a secret, it is thought he will play a villain.
Rumours about the cast for the third 'Batman' movie have been circulating for months and Sir Michael Caine recently revealed he "assumes" he will be in it.
The 77-year-old actor - who has starred as butler Alfred in 'Batman Begins' and 'The Dark Knight' - believes the third film will begin shooting in spring 2011.
He said: "There will be a new 'Batman'. It will probably start in May next year. I assume I'm there, but in the movie business you never believe anything, you assume.
"But I've been in the last four Chris Nolan pictures, he's my lucky charm. I did 'Prestige', and recently 'Inception', I'm hoping to do another one. He's written the new one."
Christian will once again take on the role of Batman.
