 In one of the final scenes where actor Elias Eliot is thrown up  against a wall, which collapses all over him, it was never planned  for the wall to do this. The building in which the scene was shot,  was an old ruin with run down walls. Everyhting on the walls were so  loose that the impact of someone being thrown onto it, made half the  wall come down. The shot ended up being a one take, with no harm  done to the actor.
