Robert Downey Jr.Robert Downey Jr. and Jude Law are currently hard at work on the sequel to Guy Ritchie's 'Sherlock Holmes,' and 'Entertainment Tonight' has been kind enough to share the first behind-the-scenes look at the film's progress.

'ET' cameras paid a visit to the set recently, where they were greeted by an unsettling sight: star Robert Downey Jr. in drag. Too bad Ricky Gervais didn't know about this -- he could have worked it into his comments at the Golden Globes on Sunday night.

RDJ and his co-star sit down and elaborate on why they've reunited with director Guy Ritchie to make a sequel (they had so much fun making the first film that they felt the need to come back for more) and the nature of their characters (they're as co-dependent as ever). We get a look at new co-star Noomi Rapace in action too. Watch the interview after the jump.
