“The plot of the movie is based on an existing conspiracy theory that NASA got Stanley Kubrick to film a fake moon landing just in case the real one didn’t work,” Grint explained to uInterview. “And they send out Ron Perlman, a CIA agent, to find Stanley Kubrick.”

In search of Stanley Kubrick, Perlman’s character Kidman seeks the assistance of a talent agent named Jonny, played by Grint. Before Jonny can explain that Kubrick isn’t his client, Kidman drops a suitcase full of cash on his desk. Instead of confessing the mixup, Jonny recruits his pal Leon (Sheehan) to impersonate the famed director.

Together, Grint, Sheehan and Perlman had a lot of laughs on the set of Moonwalkers, a farcical comedy directed by Antoine Bardou-Jacquet.

“There’s a scene where Ron’s character comes back and sort of figures out what’s happened and everything and is threatening to burn our crappy apartment down, and the three of us were laughing so uncontrollably in the scene,” Sheehan revealed. “Laughter that has gone beyond the funny or the rational. It’s sort of muscle memory laughter that you can’t undo. The more you try to fight against it the more it gets you. So we had to abandon that scene.”

Working with Perlman, who recently starred on the decidedly unfunny Sons of Anarchy, proved humorously difficult, as he had a habit of pranking people in between scenes.

“[Ron] had gone around pinching people’s bums, giving people purple nurples, having one of them shocking things in his palm whenever you shook his hand,” said Sheehan. “I’ll tell you, clowning around Perlman.”

As for whether or not Grint or Sheehan actually believe it’s possible that Kubrick helped NASA fake the moon landing, the two actors think it would be more likely that the moon is a massive egg. “We don’t know, we really don’t know,” deadpanned Grint.

Sheehan chimed in, “It could be!”

Moonwalkers is currently in select theaters. It will be available on DVD Feb. 23.
