When Julian and Sonny are going over to Vanessa's(Kristy Swanson) apartment, Sonny gives Julian a pair of "magic" sunglasses. Look behind Julian the entire time. You see people eating at a table behind him, the next shot they are gone.
Does it really matter? They could have been done. It's not that big of a deal. It could have been a cow giving birth coming in and out of the shots, and then maybe i would have cared.
NOT TRUE!!!! If you watch the scene when they are about to cross the street, the people are still there.....the camera just took another angle, so that is why it seems to have changed. But look closely the same people are still there.
A slip-up is supposed to be something that could have been easily avoided and obviously they could not have easily avoided it. It is not like they could have asked those people to stay there because they wanted the scene to be the same all the way through. They probably had to do this scene in several takes which would make it almost impossible to keep everything in the background the same.
