Continuity mistake: When Caswell walks toward the phone booth and the woman exits, she passes on his right side and walks down the sidewalk. Later in the scene Caswell gets trapped in the phone booth and breaks the window to get out. When he breaks the window, notice that the phone booth is no longer located on the sidewalk, it is now magically next to a building. (00:14:45 - 00:15:25)
Factual error: Caswell acts surprised at the sight of the lighter, but lighters were around in his time.
Suggested correction: The modern lighter, which use ferrocerium to create a spark, was developed in 1903. Caswell was from 1880. This would have been different then anything he would have seen.
