Hunky actor Bradley Cooper was amazed by his own rippling muscles in 'The A-Team movie,' so much so he was adamant that his head had been superimposed on a model's body when watching playbacks.

The 'Hangover' star plays Lieutenant Templeton 'Faceman' Peck for the movie version of the hit 1980's show, and to get in shape he cut out all sugar and salt from his diet while beefing up for the role.

After filming a fight scene with Irish co-star Liam Neeson, the film's Irish American director Joe Carnahan (who's ancestors hailed from County Donegal) called Cooper over to watch the clip - and the star couldn't believe how buff he looked on camera.

Cooper told Details magazine, 'I had to literally transform my body. As the movie progressed, I got in increasingly better shape. There's this one fight scene with Liam Neeson toward the end, where it's, like, the apex of the work. We finished and Joe's like, 'Brother, come here, look at this,' and he played it back, and I swear to God, it looked like my head was digitally superimposed onto someone else's body.'

'I was like, 'This cannot be me - that's the way I look?' It was so surreal, because as a kid I only fantasized about looking that way.'
