Mark Wahlberg has said he didn't trust anyone else to take on the role of Micky Ward in 'The Fighter' except himself.
Mark Wahlberg took part in 'The Fighter' because he was the only person who could make the story "believable".
The actor plays Irish/American boxer Micky Ward - who went on to win a welterweight world championship - in the David O. Russell sports Drama and he insists that although he wanted to play the "champ" he also didn't trust anyone else to play the role as well as he could.
He told Deadline.com: "There was always one role for me to play, and that was The Champ. I wasn't giving up the belt. And look, who else was going to play that part and be as believable as a guy who could win the welterweight title?
"I love so many boxing films. What I wanted to do was to create the most realistic boxing in the movie and look like I could win that title."
He explained: "From a practical standpoint, if you work out for two years and then you don't do it again for six months, you're back to square one. It's not like riding a bike, where you get right back on it. That training process was as expensive as it was time consuming. It wasn't like somebody else was footing the bill."
