Robert Pattinson ''almost knocked'' himself out while filming 'The Rover'.

The 28-year-old actor admits he came very close to badly injuring himself while shooting the opening scene of his new movie 'The Rover' alongside his co-star Guy Pearce last year.

Speaking to a small audience at a Meet The Filmmakers event at the Apple Store, Regent Street in central London, he explained: ''I like to do anything that allows me having to not act at all, so our first scene when Guy's throwing me around with the car, I actually almost knocked myself out, letting myself go.''

The British star plays a young southern American hunk named Rey in the ''dark and dirty'' Western, who fled to Australia 10 years before following an economic crash.

Robert wasn't ''entirely sure'' what accent he had developed for the role, but insists dialect is the first thing he thought about when he was offered the part.

He said: ''I spent a lot of time thinking about the character, 10 or 11 months from the audition, so before we started it was fairly close to me.

''With this one, I started with the voice. Trying to find little vocal patterns, gimmicks, coming up with a subtext, and creating little twerks.''
