Keira Knightley is ready to party – with her cast and crew of Atonement, which topped the list of Golden Globe nominees on Thursday, with seven nods, including one for herself and another for her leading man, James McAvoy, as well as for the WWII drama itself, as best picture.

“It’s just so exciting that we’ve got nominated in so many categories,” the British actress, 22, tells the Associated Press. “There’s such a big group of us that can get to go together. It will be a real celebration for the film. It will be a wonderful night.”

Atonement’s supporting actress nominee Saoirse Ronan is all of 13 years old. The Dublin-born teen, currently in Pennsylvania to shoot her new movie The Lovely Bones, tells PEOPLE: “I started doing films two years ago [but] I never expected anything like this would happen. It’s really lovely.”
