Revealing mistake: The location of George's burn barrel (with flames shooting out) was altered to accommodate filming. At times, there could not have been enough space between George and Fr Daniel for the burn barrel to even be between them (and without catching their clothes on fire). (00:17:45 - 00:18:42)
Revealing mistake: The possessed "Helen" that Fr Daniel threw to the ground by grabbing the back of her hair landed like a stuffed doll, not person. The "body" was mostly padding and the fake "Helen" kind of bounced or teetered after hitting the ground. Also, her arms stayed hidden in front of her whereas a real person would be stretching out or moving arms to try to land as safely as possible. (00:21:35)
