Luke WilsonLuke Wilson has revealed he took his time pouring over pictures of men’s bottoms to find a butt double to represent his posterior in his new film My Super Ex-Girlfriend.

He said: “What they do is they give you photos of different guys’ backsides and have you pick one out.”

“I found myself poring over the Polaroids and saying, ‘I like that one but it doesn’t have quite the pizzazz I want for this scene.’ Or, ‘This one’s good, but it’s too muscular’.”

“I’ve got a little bit of damage back there. As you get a little older, you get little dents and indentations. You want to act cool about it when you eventually say, ‘I like this guy’s a**.’”
