Cert 15 Stars 3

In this remarkably odd black comedy, former Harry Potter star Daniel Radcliffe takes on his most fantastical role yet.

He plays a farting corpse called Manny, who inspires a shipwrecked soul to use him as a jetski to the mainline. After this curious beginning, it all becomes a bit weird.

On his mission to return home, Paul Dano’s Hank utilises the cadaver as a host more practical devices, such as a compass and a gun.

There’s a wonderful chemistry between Dano and Radcliffe, even if the biology and physics are tested to their limits.
