Chilean actor Pedro Pascal was left with bruised and battered knees during filming for hit fantasy series Game Of Thrones after constantly hitting himself with his own prop spear.

The Graceland star was cast as Prince Oberyn Martell, aka The Red Viper, last year (13) for the new fourth season of the show, but Pascal admits it took him a while to get to grips with his poisoned weaponry and he ended up injuring himself on multiple occasions.

He tells the New York Times, "The worst of it was whacking myself with my own prop. I busted up my knees a lot trying to spin the thing from my left to my right. I whacked myself in the face several times. But I was never hurt by another actor or fight choreographer."
