Reese WitherspoonReese Witherspoon has revealed that the height difference between her and co-star Vince Vaughn caused some problems on the set of their new film Four Christmases.

The pair, who play a couple in the festive film, are divided by 15″ and Reese explained recently: “He’s 6′5 and I’m 5′2.

“We had a really funny scene, I don’t know if it’s in the film any more, where he rolls over onto me. We were in bed and then at the very end he rolls over and goes to sleep, but he rolls over and lays on top of me. It was like a tree trunk had just landed on me. I kept going, ‘Tim-berrrrr!’ It was really funny.

“[The rest of the time] I stood on a lot of boxes and they had to build ramps that were about the same size as where I should be. It was a challenge, especially the kissing scenes. It was hard to get up there to kiss him but we worked it out.

“And he had to pick me up for half the dancing. He’s actually holding me in the air so we can stay in the same frame. He’s a fantastic dancer. A very, very good dancer, which you’d probably figure from Swingers. They were teaching us dance moves. I just couldn’t keep up and he was like, ‘Oh, it’s a one-two cha cha cha’.”
