The screen legend, who voices Finn McMissile in Pixar's new release Cars 2, admitted that he wouldn't rule out returning to the series as the Gotham superhero's butler Alfred.
The Dark Knight Rises director Christopher Nolan has previously claimed that next year's superhero blockbuster will conclude his Batman trilogy. The franchise will then reportedly be rebooted by Warner Bros.
"I think it will be the last Batman that Chris Nolan will make. I never say the last time for me for anything," Caine said.

Caine confessed that he was once told off by director Nolan for revealing that a new Batman movie was going intro production, saying: "When I got on the set Chris Nolan said, 'You told someone you're doing Batman!' I said, 'Jesus, how secretive can we be?'"
Of his involvement in the latest sequel, Caine added: "I can tell you we're halfway through it. We finished in England, my next lot [of filming] is in America. And it'll be great."
