The episode of The Ellen DeGeneres Show, which airs Wednesday, Oct. 8, includes a conversation about the success of Affleck's new movie, which zoomed to the top of box office charts over the weekend.
And Garner, 42, isn't coy about the reason her hubby's movie is getting such buzz. "He's showing his penis," she concurred, when DeGeneres suggested this might be helping ratings. "I think you're probably onto something. What I have to say is, 'You're welcome.' I just try to consider myself a charitable person and I wanted to give back. You give me so much, I wanted to give something back to all of you," she joked. Find out more details about Affleck's nude scene.
When asked whether this was the first time her husband had been in a full frontal nude scene on-screen, the actress replied, "Outside of our very racy film home? Yes."
"Did you talk about it?" DeGeneres asked.
"It wasn't a discussion, it was like, 'Hey, at work today [David] Fincher talked me into coming out of the shower.' And I was like, 'Oh, cool, well, I hope he had on a wide lens.'"
