Jeremy Renner has a samurai sword under his bed to ward off intruders

The 'Mission: Impossible - Ghost Protocol' star explained he doesn't feel the need to implement a high-tech security system in his home because he has already developed a slightly more unusual way to protect himself.

Jeremy said: "I have an actress friend who is being stalked at the moment. It's scary stuff, but if a girl ever does that to me, what's really going to happen?

"I have a shotgun and a samurai sword under my bed, so I'm protected."

The actor - who has also taken on physically challenging roles in 'The Avengers' and 'The Bourne Legacy' - admitted 'Mission: Impossible - Ghost Protocol' has been the most "gruelling" part he has taken on after having to learn "fast hands boxing" and "Filipino stick fighting" for the movie.

He told the Sunday Telegraph newspaper: "Of all three films, the training for 'Mission Impossible' was by far the most gruelling."

"Some of those techniques have a real balletic beauty - even if they are basically about taking someone out as quickly and efficiently as you can."
