Keira Knightley terrified of starring in a comedy

Actress Keira Knightley has revealed she is terrified of starring in a comedy, saying that she would feel uncomfortable making a fool of herself on the big screen and insists she is too "dark" to be funny.

The 'Pirates of The Caribbean' star, 22, 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," she said.

"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 also revealed that she loves going to the movies and watching a film 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."

Keira also said that she shared a bath with actress 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."
