Australian actress Melissa George was "seriously injured" as she prepared for her role in a new U.K. Tv drama and has lasting problems as a result of the accidents.
The star took up martial arts to play an espionage operative for a private intelligence agency in upcoming series Hunted, and the training left George battered and bruised.
As a result, she still experiences issues with her hip and right hand, but George is delighted with her new skills.
She tells The Sun's Tv Magazine, "I spent months learning a martial art called Keysi and I got seriously injured a couple of times.
"I still can't close my right hand and my hip is damaged, so I can't get out of a car like I used to. But I can kill a man with my bare hands. I frighten myself nowadays."
Hunted debuts in Britain on Thursday (04Oct12).
