Rachel McAdams and Channing Tatum are set to warm audience's hearts in Columbia Pictures' upcoming romantic movie, "The Vow," but when it came time to shoot the movie's racy scenes, Channing had a few tricks up his sleeve - and down his pants!

“He bared his ass quite a bit,” Access Hollywood correspondent Tim Vincent said of Channing’s performance to Rachel at the film’s junket.

“He did bare some other things. Yeah, he goes for it,” Rachel said with laugh.

In the upcoming movie, the actors share a scene where Rachel’s character walks in on Channing’s character completely naked, a scene that the actor employed the help of the prop department on to enhance his nether regions.

“He’s very generous, giving, thoughtful actor. He went to the prop department like a month in advance and said hey, ‘I want to help Rachel out in this scene. I don’t want her to have to pretend too much,'” Rachel explained. “He had a prosthetic made!”

Channing told Access that he worried about Rachel’s reaction skills for the pivotal scene.

“I really didn’t have faith in her acting, to be totally honest. I wanted to get a real reaction from her, because it needed to be good,” he joked. “I made sure that I had [a prosthetic] that was down to my shin and that take is in the movie.”

“The Vow” is the real-life story of a young couple who were struck by tragedy shortly after their wedding. A car crash puts the wife (McAdams) in a coma, where she is cared for by her devoted husband (Tatum). When she comes to, without any memory of her husband or their marriage, the husband must woo her and ultimately win her heart once again.

Opening across the Philippines on Friday, Feb. 10, “The Vow” is distributed by Columbia Pictures, local office of Sony Pictures Releasing International.
