Other mistake: In the scene where Jolie drops Depp off at the airport she asks him to tie them off. Depp does so with a solid knot. Jolie then unties the knot from the boat side and leaves him behind. The rope should still have been looped around the mooring where Depp attached it, and hanging in the water where she untied. It is completely gone.
Other mistake: Elise orders a "Croissant" which you probably know is a "c" shaped pastry. However when she starts reading the letter, her order is not a croissant but a "pain chocolat" instead. This is a different shaped pastry with chocolate inside. (00:02:20 - 00:04:40)
Other mistake: Towards the final scene we see Frank and Elise drifting away in a sailboat that moves forward but the sail is not up.
