Continuity mistake: Just before the lights blowout Mitch comes back into living room and there is a red ottoman to the right of the green chair that Lydia and Cathy are sitting in. A few moments before, all three of them just walked through that spot when they were hiding by the bookcase and it wasn't there. (01:44:05)????
Continuity mistake: There's a fixture with a wire hanging down from it in the front left corner of the restaurant. When they built the interiors for this scene they forgot to put it there and when Melanie opens the phone booth door trying to get out the wire hanging from the bottom of the roof of the restaurant is missing. In the close-up as Melanie tries to get out the cord that we saw previously sticking out has been tucked back in towards the phone for this shot. (00:26:25 - 01:26:45)????
Continuity mistake: As Melanie and Mitch walk past the side of the restaurant look closely at the second and third windows from the right. Now we can see right into the place through these but after they walk into the restaurant look behind the bar all three windows have drawn blinds. (00:26:25)????
