Robert Downey Jr. Sherlock Holmes Press Conference (Video)

Hi there, I'm Lauren Bradshaw. Robert Downey Jr. reveals the secret to his chemistry with his Sherlock Holmes costar Jude Law in today's PopSugar Rush. RDJ: "We have been sharing a suite during the entirety of the press junket. We've asked for a small room with a single bed . . . Robert Downey Jr. will do just about anything to get into his role as Sherlock Holmes. Robert sat in on the press conference for the sequel Sherlock Holmes: A Game of Shadows in London yesterday, where he joked about sharing a bed with costar Jude Law and the romantic undertones of their characters' relationship. RDJ: "As for wearing each other's clothes or cross-dressing to please each other, that's something we're going to save for the next installment." RDJ [in drag]: "I agree, it's not my best disguise, but it'll make due." Holmes and Watson's flirty bickering was one of the highlights of the first movie, and Robert and Jude have clearly had fun playing it up to maximum effect. JUDE: "I'm not going out with you dressed like that." . . . But in all seriousness, Robert says the main secret to the guys' onscreen spark is all about mutual appreciation of one another. RDJ: "Look, people talk about chemistry and what that means, and we were just having lunch trying to figure it out and we're grateful it comes across that way. We work really hard, we have an immense respect for each other . . . " You can see Robert and Jude together again when Sherlock Holmes: A Game of Shadows comes to theaters on Friday.
