Sean Penn would probably just say he had "minor traveler's flatulence," but Daniel Radcliffe's character in the new movie "Swiss Army Man" is a farting corpse whose many, many toots help Paul Dano's suicidal castaway reach safety. (Turn away, Ginny Weasley!)

The surreal indie premiered to a packed Sundance crowd, but Variety noted that the movie "could win the festival's award for the most walk-outs, as a continuous stream of audience members kept standing up and bolting for the door throughout the film."

As they added in a mini review/report:

"The story unfolds in a magical realist style and features long discussions about masturbation, isolation and the meaning of life. It also features a kiss between Dano and Radcliffe (who continues to flee his Harry Potter image by taking part in a reoccurring gag where his dead character maintains an erection)."

OK then. Viewers seemed mixed on the movie, with one tweeting, "I just watched a 90-minute fart joke, but it was a wholly original one."

If you think DanRad and company are upset by the reactions, you're dead (and tootin'!) wrong. Co-writer-director Daniel Kwan even repeated some of the "amazing" headlines, like "Daniel Radcliffe Farting Corpse Movie Leads to Walkouts," telling The Hollywood Reporter, "I couldn't have written them better myself."

THR asked Dan if he ever imagined being in a movie with headlines like that. "No, obviously not," Dan said with a laugh. However, he said of the film, "It was great and original and exciting and completely mad, and unlike anything else I've ever done or read." He said he loved the physical challenge of doing his own stunts, and was drawn to the idea of challenging viewers. "I love that it's this perverse and mad. ... It's exciting, to be honest, using farts as something other than comedy, like using them for plot and actually emotion and making some people super uncomfortable. ... I think there is something wonderful about it."

Sounds like they have zero regrets and maybe even love the walkouts for bringing more attention to the film. All publicity is good publicity, right?
