SKULLHe’s a blue-collar gravedigger by day and Skull Man by night, when he turns into a bloodthirsty cardboard-combat cannibal. This is a fresh trailer for Justin McConnell’s Box Wars doc Skull World and it looks like fun.

Greg Sommer a.k.a. Skull Man is the mastermind of a Canadian branch of the international underground fight club Box Wars. What these grown people do is “cardboard Braveheart battle” dressed as robot reapers, lobster-monsters and burning joints.

It falls somewhere between rodeos and Jackass on the performing arts spectrum, with extra credit for Dada gigantic “brass” knuckle props, but a slight deduction for not being dangerous enough. Prove me wrong, Skull Man. Prove me wrong.
