Angelina Jolie was injured several times while shooting Salt.

The actress, who plays tough CIA agent Evelyn Salt in her latest movie, says she felt "dumb" for being left battered and bruised after filming.

"I got lots of bruises and things and I got a little teeny nick right between my eyes," she said.

"I banged straight into a table while I was shooting somebody and jumping sideways. I felt really, really dumb. I just lay there with a big icepack on my head and I was bleeding down my face. But then we used it in the movie. I get bloody in the movie anyway, so..."

Jolie recently said she looks "rough" in Salt, which is about a CIA agent who is on the run after being accused of being a spy and disguises herself by changing her hair colour to blonde.

"Females in those films rely on being female but we wanted to ignore that - she's just Salt," she said.

"She doesn't use her sexuality to get anything. In fact, in many ways it's the roughest I've looked because when you fight it gets ugly and if someone breaks your nose it's not pretty."
