By now, you've probably heard about Swiss Army Man – the eagerly anticipated, divisive indie flick in which Paul Dano rides Daniel Radcliffe's farting corpse like it's a jet ski. It's so unabashedly bizarre that it prompted walkouts when it premiered at the Sundance Film Festival last week.

Turns out two of the members of Atlanta's Manchester Orchestra – Andy Hull (above right) and Robert McDowell (left) – wrote 74 minutes of music for the film that Vanity Fair called (possibly) "the strangest movie in Sundance History." And the guys couldn't be more proud.

The band posted on Facebook: "We scored the coolest and weirdest movie at Sundance. I can't wait for everybody to see this movie."

Directed by music video duo Daniel Scheinert and Daniel Kwan (the Shins, Foster the People), Swiss Army Man is a fable about a hopeless man stranded in the wilderness who discovers a mysterious dead body (Radcliffe, aka Harry James Potter). Once Dano's character realizes the corpse is the key to his survival, he's forced to convince the dead body that life is worth living.

It's the first movie score for Hull and McDowell, who attended the premiere at Sundance in Utah. Hull posted that they'll now spend the near future producing the upcoming effort from All Get Out, "then it's Manchester time."

Manchester Orchestra last released their fourth album, Cope, in 2014, then an acoustic reimagining of the entire album called Hope a few months later.
