Factual error: During the arbitration supposedly set in Austria, we can see at first glance a British Coat of Arms in the top of the wall of that beautiful room. No official Austrian building would display a foreign coat of arms - the scene was filmed in Britain.
Factual error: While driving through Los Angeles (with Helen Mirren and Ryan Reynolds) you can see a Guardians of the Galaxy movie billboard through the front windscreen. This movie is set in the late 1990's.
Character mistake: When driving to the airport Pam Schoenberg is talking to Maria Altman and referred to her as Ms. Adel instead of Ms. Maria or Ms. Altman.
