Butterfly Effect, The - Two Posters on the Same Door?
When Evan is looking for something to protect himself with from Tommy he first walks into the room and there is one poster on the door... When he said "Maybe one of the frat guys has a guy" and kayle yells at him there is clearly a different poster on the same door... Magic Trick or Mistake
They are different doors. The second door shown has the first desk which was searched next to it (it has a monitor on it), the first door has a set of drawers next to it.
