The star admits he would jump at the chance to join the cast of Nolan's third 'Batman' outing, but would understand if the director decided not to pick up where 'The Dark Knight' left off, out of respect to the late Heath Ledger, who played The Joker.

'If Chris asked me back, I would love to. Heath really was meant to come back as The Joker (for the next movie) as we all would want him to do so, maybe this will be the way it is and be its own little thing,' he said.

Ledger died from an accidental drug overdose in January 2008.
