The Sundance sensation Swiss Army Man essentially wonders what Cast Away would have been like if Wilson weren’t a volleyball but a corpse named Manny (played by Daniel Radcliffe) whose bodily functions like farting and boners helped our stranded protagonist Hank find his way home (the farts propel Manny over ocean like a jet ski, and his boner works as a compass). What flourishes is what one of the movie’s directors, Daniel Scheinert, deems a “gray love story.” Swiss Army Man is, in a word, insane.
