Factual error: When Marv is talking with the Priest in the confessional, he cocks the hammer of his pistol as a means of interrogation. But in the next shot, the pistol is uncocked, without sufficient time for this to occur. In fact, the pistol is uncocked even when Marv shoots him. This cannot happen, since his pistol is a standard 1911 .45, which requires the hammer to be cocked in order to fire.
Factual error: In the scene where Bruce Willis is confined in the hospital, where he is talking to young Nancy, a volume respirator can be heard, yet Willis is not intubated and no other paraphernalia are attached to his larynx and only intravenous lines are present.
