To do a B-movie right, to straddle without crossing the precarious line between hilarity and stupidity, is no small feat. Jason Eisener achieves it with Hobo with a Shotgun, which reaches heights of comic literal-mindedness that the comparatively mild Snakes on a Plane could not. This is, yes, a movie about a hobo with a shotgun, but it’s also an inspired parody of the post-apocalyptic whack-a-mole revenge flick, a film with stronger than expected acting and an ideal dose of energized mania. The immortal Rutger Hauer stars as the titular hobo, who rides the rails into a lawless town populated by seething, ranting maniacs of all stripes. The debauchery is too much to handle – the hobo’s first day in, he’s greeted by a man filming bum fights and an extended set piece in which resident super villain The Drake (Brian Downey) beheads his brother in full view of the public, after which his scantily clad mistress gyrates and devours the fountain of blood. The baddie and his sons (Nick Bateman and Gregory Smith), nightmarish versions of ’80s Tom Cruise, exert a stranglehold over this decaying, crime-ridden megalopolis, where plumes of smoke pour over the streets and gritty, yellowed industrial building mix with seedy punk-populated arcades.
