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.
Continuity: When Lucille throws the pills to Marv, he catches it with his left hand (while holding a cigarette in his right hand). The shot changes immediately to a close up on the pills in Marv's right hand. Then in the next shot Marv takes the pills, but has to take the cigarette out of his mouth first.
Continuity: When Marv jumps off the top floor of the hotel and grabs onto a rail and then jumps over it to dodge the bullets, if you watch closely, when he lands you can see that the shot is actually made out of two separate shots blended together. Watch carefully as he leans forward after the land, he's closer to the camera in the second shot and his movement is not perfectly synced to the previous one.
