Misha was first cast a priest in the 1973 horror classic 'The Exorcist'. However, the movie was thrown into chaos during filming of the infamous exorcism scene, as the Devil flew out of Regan's body the instant Misha told it to and refused to get back in until Misha was removed from the set. The reason why remained one of Hollywood's biggest secrets until the Devil's 2001 autobiography, 'I Am One Evil Bastard', where he said 'Everyone knows you don't fuck about with Misha Collins. If he says jump, you ask how high'.
