Bang Showbiz quotes the Welsh actor as saying: "Playing a terrorist is absolutely no fun at all. It's bad, completely uncomfortable, and it's a tough shoot, but it's very enjoyable to be working with the director, Gregor Jordan, and a really great script, so I'm excited about how it's going to turn out."
Despite his discomfort, Sheen insisted that he is pleased that the role has given him the opportunity to master an American accent. "I'm really enjoying that. It's sort of the first proper full-on American character I've played," he said.
Sheen can next be seen in Frost/Nixon, Ron Howard's drama recounting Sir David Frost's interview with shamed US President Richard Nixon.
