Stupidity: Mason should have also removed the other gun he had in his office for display, or he could have removed the bullets from the guns. There is no reason he would have to use these guns for his victims, so it makes no sense to leave the other gun in his office or have them loaded with bullets.
Vacancy (2007)
1 stupidity
Directed by: Nimrod Antal
Starring: Kate Beckinsale, Luke Wilson, Ethan Embry, Frank Whaley
Continuity mistake: When Luke Wilson grabs the first video off the top of the TV that one has the label pulled off, But the piece that was left was whole. But when it cuts to him putting it in the VCR the piece that was left was two pieces, Then when he takes the first video out and puts in the second one it is the one with the two pieces of label on it.
