Ghost or Extra?
Watch the movie until the exorcism scene. Watch as the 2 guys are fighting, but look past them to where the stairs are in the background. You will see a man walk by in pants and a white shirt. This is not one of the guys in the movie as they are fighting. As they are all supposed to be locked inside by themselves, there should be no other actors around. Ghost?
Tucked or Untucked?
Early on, Ryan untucks her shirt because she's afraid of being "touched" by a ghost - yet in subsequent scenes her shirt remains tucked in for at least 15 minutes. Finally, after much running around and scene edits, her shirt magically becomes untucked again.
