Daniel Craig Calls 'Dragon Tattoo' Very 'Adult' Movie

'Babysitters are going to get, hopefully, a lot of money out of this film,' Craig says, predicting the mature set will flock to theaters.

Rape, murder, intrigue ... the feel-bad movie of Christmas may not leave audiences feeling bright and merry but "Girl With the Dragon Tattoo" star Daniel Craig suspects the dark drama will inspire smiles among at least one group.

"Look, I'm a David Fincher fan, so it was an easy choice to make when accepting this film," Craig told MTV News at the film's New York City premiere. "It's a great story. It's an adult movie. The babysitters are going to get, hopefully, a lot of money out of this film. That's why I wanted to get involved."

The film, based on the novel by late Swedish author Stieg Larsson, follows journalist Mikael Blomkvist (Craig) as he tries to solve the 30-year-old murder of teen Harriet Vanger, with the help of asocial hacker punk Lisbeth Salander (Rooney Mara). Mara has been earning raves for her performance as the damaged heroine and even netted a Golden Globe nomination on Thursday. Craig said he had no doubts as to the newcomer's abilities.

"We all knew she was good. She's just committed as an actress, and she made all of the right choices with David's help and everyone else's help," he said. "She's just blossomed as somebody. As I said, we knew from the beginning that she was good enough — it was everyone else who had the problem."

Best known for her work in Fincher's "The Social Network," Mara returned the compliment, expressing gratitude for Craig's help and guidance on set. "Daniel is an incredible actor, and I don't think we've seen him in a role like this before, and he's brilliant," she said. "I couldn't have asked for a better person to sort of have my coming out. He was very patient and generous with me."

"The Girl With the Dragon Tattoo" opens December 20, a day earlier than its initial release date.
