Ben Affleck Talks 'Gone Girl' Full-Frontal Shower Scene with 'MTV News' [VIDEO]

Ben Affleck's penis is the star of his new movie, Gone Girl.

In an interview with MTV News, the star talked about a sexy nude scene involving his character, Nick Dunne.

"I think there's some brief nudity in this movie," he said. "Director David [Fincher] said to me from the beginning, 'This is a warts and all movie. It can have no vanity. You have to see the naked underbelly of this character. It's gotta be like in Europe, they just don't give a s--- about any of that stuff and they just play real people.' ... [So] there is some brief, very brief nudity, I think."

Based on the book by Gillian Flynn, the film centers around Ben's character, who becomes the lead suspect in the disappearance of his wife.

The controversial scene in question occurs when a nude Amy Elliott-Dunne (Rosamund Pike) is taking a shower and is then joined by her naked husband. When he gets in the shower with her, you see a shot of his penis.

The Batman v. Superman: Dawn of Justice actor continued to have fun with the interviewer about being full frontal on the big screen.

"I try to get it in every movie," the actor joked. "The penis is in there! It's IMAX penis! You've gotta pay 15 bucks to see it in 3-D. It looks better in 3-D."

In case you are too judgmental about Ben's private parts, he warned, "It was a very cold set. It was freezing. It was subzero."

Gone Girl opens Oct. 3.

Are you as excited as we are to see Ben's ... umm ... acting?
