Scottish movie hunk Gerard Butler is thrilled with his look in war epic 300 - because his warrior role gave him a great bottom. The actor worked out religiously to play a Spartan king in the film, and admits he not only developed a six-pack and a defined torso, he also pumped his backside into the best possible shape. He says, "I don't have the biggest arse in the world... In the PHANTOM (OF THE OPERA), Joel Schumacher (director) was always like, 'I want you to have these peasant, strong thighs,' so he padded my arse. "But, for this, I was doing like 100,000 squats... with weights and chains and I just noticed I started getting this Jennifer Lopez arse. It was quite amazing."
