Keira said: "I am a big fan of 'Blades of Glory'. I don't normally watch films like that and it was great. But getting involved in a Will Ferrell comedy would terrify me."
The 'Atonement' actress has revealed she would be uncomfortable making a fool of herself on the big screen and insists she is too "dark" to be funny.
Keira said: "I am a big fan of 'Blades of Glory'. I don't normally watch films like that and it was great. But getting involved in a Will Ferrell comedy would terrify me.
"I guess I am into darker things at the moment. I think I am quite frightened of comedy. It's never something that I've watched a lot of. I think people can always quote comic films and I've never been able to do that. I can quote you the tragic ones, but not the comic ones.
"I can't watch myself at all. I'm not really interested in trying to look at myself in a film and go, 'Yeah, good job.' I'm incredibly critical. And I like being critical - I like watching it and picking it apart."
Keira loves going to the cinema and watching a movie which leaves her in tears.
She explained: "I like a good cry. I think those are the films I like the most. I like ones that make me cry. There are millions of movies that make me cry. Pretty much anything. I cry at anything."
The 22-year-old star also revealed she shared a bath with Sienna Miller in a scene for 'The Edge of Love'.
She said: "We did get in the bath together, yes. Washing our knickers in the bathtub."
