LOS ANGELES: Katherine Heigl was left nursing a number of nasty bruises after shooting new movie Five Killers because she kept falling over on set.

The actress was involved in a number of action scenes in the film, in which she stars as a woman who marries an assassin, played by Ashton Kutcher.

But Heigl reveals she was so clumsy, she was constantly having to treat bruises she picked up - and the accidents have put her off appearing in any more action movies.

She says, “I’m not a fan of the action genre! It was actually sort of painstaking and I’m the most uncoordinated clumsy, klutzy person. I always had a bruise, I always tripped and fell.”

“I’d be trying to look serious running while a car tries to chase me down and I would still look stupid. I realise I’m not really built for it! I think I’ll give it a go one more time, but I might have to get in shape beforehand!”
