(Cover) - EN Showbiz - Dominic Cooper has revealed he is "terrible to work with".

The British actor is currently promoting his upcoming film The Devil's Double, in which he plays not one, but two roles.

Portraying both Saddam Hussein's son Uday and the man forced to become his body double, Latif Yahia, meant that Dominic had to act with footage of himself in many scenes.

"I'm terrible to work with, actually. I've always known that," the star joked when speaking to MTV.

Dominic revealed what it was like to portray such extreme parts, saying he rather enjoyed the role of Uday. Dominic also explained how it was possible for him to interact with himself on camera.

"[Uday is] so extreme and having that flexibility and deliberation to just go as crazy and berserk as I liked was exhilarating but it was also very technical the way in which we had to film it," he said.

"We would film things and the camera had to be in a memory lock and reshoot the scene exactly as we'd done it for me to be able to step in as the other character and reshoot it so more often than not I'd be acting opposite no one." (C) Cover Media
