In the upcoming film, Swiss Army Man, Daniel Radcliffe plays a corpse that washes ashore on a deserted island.
He's discovered by Paul Dano who is both shipwrecked and suicidal.
And in the trailer we've already seen for the film, things get pretty...intense.
Now, thanks to a brand new trailer, we have even more insight into what goes down between these two.
Most notably, Dano uses Daniel Radcliffe's boner as a compass to help guide him home.
Yep, that's his boner. Again.
Swiss Army Man hits theaters on June 24.
