Would James Franco Ever Have Sex Onscreen?

'Interior. Leather Bar.' co-director tells MTV News he'd consider it 'under the right circumstances.'

Things get really real in "Interior. Leather Bar." — including the sex scenes.

The film is James Franco's re-examination of Al Pacino's 1980 flick "Cruising," and it has some real-life sexy times in it. While Franco avoids getting in on any of the action in the NSFW flick — which just debuted at the Sundance Film Festival — he did tell MTV News that, for the right project, he would consider pulling a Shia LaBeouf and have sex for real with the cameras rolling.

"I'd say under the right circumstances. There are a lot of circumstances," he said, with co-director Travis Mathews by his side. "Who's involved? Both behind-the-scenes, behind the camera, in front of the camera."

So, what would that perfect project be? Well, maybe he'll do it for Michael Bay in the next "Transformers" flick. "OK, well that's all you had to say ... duh!" he laughed. "Sounds like a blockbuster to me!"

Sex and Sundance: Was this year the raunchiest on record?

Of course, sex as been at the forefront of many a Franco project as of late, including films like "Kink" and "Lovelace," and he doesn't really get what all the hoopla is about when it comes to capturing sex and sexuality on the big screen.

"It's hard to put certain kinds of sex in film," Franco said. "Now, I could sort of understand that if it wasn't so easy to put other kinds of things in film, like violence. Obviously, there's some weird standard here that is just illogical.

"Sex and sexuality are such big parts of our lives — the ways that we define ourselves, the ways that we interact with each other," he said. "Everyone thinks about it. Everyone knows about it. Even if you insist on living an incredibly chaste life and you're chaste in your thoughts, that's a conscious and concerted effort to keep sex from your thoughts. So you're still engaging with sex even if it's in a negative capacity. It's a huge part of our lives. It's part of being human."
