Robert Downey Jr: 'I Want To Keep Playing Sherlock Holmes'

Robert Downey Jr wants to commit to the 'Sherlock Holmes' franchise for the rest of his life.

Having played the fictional detective twice now, Downey is prepared to star in the series well into old age.

He told ShowbizSpy: "My dream would be for Holmes to become to detective movies what 'James Bond' is to spy movies.

"The only difference being I don’t get retired as Holmes in favor of a younger actor. They’ll have to prise the role from my clenched fists first!"

Downey joked at a London press conference for 'Sherlock Holmes: A Game of Shadows' that he has to be disguised as a woman so much that the next installment should be titled: 'A Game of Trannies'.

'Sherlock Holmes: A Game of Shadows' is released on December 16.
