Other mistake: When Darry is in the basement under the church, Darry is laying on the floor surrounded by a circle of sunlight appearing through the pipe. Then follows a series of cuts between Trish at the open end of the pipe, and Darry. Why do we not see a silhouette of Trish on the floor rather than a perfect circle of light?
Other mistake: When the guy with the stitched up chest dies, Darry starts walking back towards the pipe. In the next shot, it looks as if he's turning around and not walking towards the pipe. It was obviously taken from the previous shot before he saw the stitched up guy.
