Noomi Rapace, who plays Lisbeth Salander in the Swedish film 'The Girl Who Kicked the Hornet's Nest,' told Cinematical that she is playing a gypsy in 'Sherlock Holmes 2,' her first Hollywood film. "My character is a gypsy," Rapace said in an interview Monday in Los Angeles, Calif. "She is a traveler and she's cool – she's a bit crazy, but I like her. I'm having a great time.

Rapace became an international sensation after taking on the title role in 'The Girl With the Dragon Tattoo,' director Niels Arden Oplev's adaptation of Stieg Larsson's novel of the same name. Since then she has fielded various offers from filmmakers all around the world, and picked Guy Ritchie's follow-up to his 2009 blockbuster 'Sherlock Holmes' as her first major American movie. Rapace said that despite the material's energetic, fun tone, she is doing a lot of research to make sure her character is as authentic as possible.

"I'm doing a lot of research about gypsies," she explained. "I'm going to Paris to visit some gypsy camps, and I'm going to Transylvania to actually see how they live. Because the gypsies are so poor, they live pretty much the same as they did then, and they keep in the traditions and all of that, so when you go to Transylvania, for example, they live pretty close to the way they lived hundreds of years ago. So I'm listening to gypsy music and I'm learning to sing and dance."

The production of Ritchie's film has largely been shrouded in mystery thus far, protecting its secrets so they can be properly revealed when the film is released on December 16, 2011. But Rapace revealed that the sequel has a similar tone to the first film, and she's enjoying exploring that kind of creative environment. "It's really fun," she said. "I like the guys I'm working with. I think [in 'Sherlock Holmes 2'], we're working in that same kind of landscape. They have created some kind of world, and it's really fun to work with them."
