(Cover) - EN Showbiz - Christian Bale is sure Mark Wahlberg protected him from being punched while shooting their new movie.

The Hollywood stars appear alongside each other in The Fighter, which tells the story of real-life boxer Irish Micky Ward and his half-brother Dicky Eklund, who helped train him.

Mark portrays the former, while Christian is Dicky, and both the sporting stars were involved in the movies creation. Christian enjoyed talking to Dicky and hearing about his life, although Dicky didnt always approve of the direction of the movie.

Initially, there were a lot of problems. Dicky would be saying, 'That's not how it went down. I said this not that,' and 'He wasn't there at that point. He was over here,' Christian explained. [We told him] 'Right, but we've had to kind of blend these two scenes, because otherwise this movie is going to be years long.' So he came to understand that, but there were a couple of moments where I had to say, 'Dicky, don't go punch [director] David [O. Russell] now. Don't go punch him. It's all right, count to ten, let's figure it out.' And I'm sure David and Mark had to stop him from punching me and stuff.

Christian explained part of the job of the film is in the relationship between the two siblings. It is that which encouraged him to take part, especially as he grew closer to the two men.

It's the roller coaster of their life that makes it a fascinating story. Each one individually doesn't make a movie, but you combine the two brothers, and there's a fascinating movie, he told MTV. (C) Cover Media
