While Robert Downey Jr. has been doing plenty of press for his upcoming blockbuster Iron Man 2, due in theaters May 7, he also revealed some new details on another sequel in the works. MTV Movies Blog recently spoke with Downey Jr. who revealed that Sherlock Holmes 2 might see his title character traveling outside of London.

"Yes, I think we'll be abroad," he said, referring to rumblings that Holmes would be leaving London behind for his next adventure. "A bit of Paris, a bit of Switzerland by the end, if I'm not mistaken."

Downey also spoke about who will return for the sequel, such as his Sherlock Holmes co-star Rachel McAdams, although it seems that those decisions haven't been made as of yet.

"It's hard to say [who is coming back]," Downey said. The biggest question mark is on Holmes' love interest in the first outing, played by Rachel McAdams. "Because Irene Adler only appeared in one of the stories of Doyle's reservoir of activities. But we'll find out quickly."
