CANNES, France—The Cannes Lions festival is mostly about real advertising, but once in a while the fake stuff sneaks in.

And in that category, none was better this year than "It's Not Porn," a video screened at the Saatchi & Saatchi New Directors' Showcase in the Palais on Thursday, where it was loudly cheered. Director Alberto Belli made the piece almost a year ago, but it got a whole new audience this week.

We won't spoil it—check it out below.

"I had heard a lot of stories from friends who are actors about the stuff they have to do on auditions," Belli told Shoot about the inspiration for the film. "Then I was watching TV one day and I wondered about a girl in a sex scene. What would she tell me if I asked her how she got the role? I thought it would be funny to play with that concept."

"It's Not Porn" isn't Belli's only viral success. He also made "For Your Consideration," a spoof of Les Misérables and actress Anne Hathaway's pursuit of an Oscar nomination.
