The rumblings out of Sundance are true: Daniel Radcliffe does play a bloated, farting corpse "Swiss Army Man," as you can now see in this first trailer for the decidedly offbeat film. Oh, what a long way he's come since Hogwarts ...

Written and directed by Daniel Scheinert and Daniel Kwan, "Swiss Army Man" stars Paul Dano as Hank, a hopeless man stranded on a deserted island who discovers a mysterious dead body (Radcliffe, naturally). Together they embark on an epic journey to get home. But as Hank realizes the body is the key to his survival, the once-suicidal man must convince a corpse that life is worth living.

Also starring Mary Elizabeth Winstead, "Swiss Army Man" opens June 17.
