The scene where Lance arrives and greets Miss Dove with "and you must be the excellent Miss Dove" is shown twice. Although both scenes should be identical in every respect, the positioning of Miss Dove in each is very different as Lance addresses her.

Just after Lance's car is spotted by the police, he drives past a modern (post-1964) speed limit sign.

End scene where Lance is talking to Patricia, you see the top of the seat-belt mounting. This takes place during the 1950s, but Lance's car has a modern 3-point seat-belt.
