Corrected entry: In the scene where Largeman and Sam are sitting on the stairs in the airport, look at the escalator to the right. In the first long shot, the escalator is moving upward. In the next shot the escalator is standing still. When it cuts to a close-up of Largeman, the escalator is moving again.
Corrected entry: In the scene where Large and Sam are sitting on the stairs at the airport, Large's watch continually shows the same exact time - even the second hand never moves.
Correction: isn't it possible that his watch battery is dead?
Corrected entry: For Mrs. Largeman's Jewish funeral, there should not be any kind of metal ornaments or handles attached to the coffin, it should only be a pine box (in accordance with Jewish law, everything must return to dust), yet the metal ornaments/handles can be seen.
Correction: Although this reviewer is correct in their description of jewish burial rituals (handles should have been rope or something organic) we must look at it in the context of this movie. If you recall, Largeman said that he wasn't strong in his Jewish faith. That fact, paired with his father's taste for expensive things (note the interior of his house), we can assume this was something Braff considered. As a personal note, I am Jewish and have been to several Jewish funerals, as well as being a pallbearer at one and all of the coffins had metal handles, so it isn't always followed exactly.
Correction: In fact, when you see the close up of Largeman after the long shot, you cannot see the escalator behind him. What you are seeing is a reflection of the stairs on which they are sitting. There is a glass partition between the stairs and the escalator and this causes the reflection.
