Continuity mistake: Agatha's nightgown strap switches between hanging down on her arm, or being up on her shoulder, normally.
Continuity mistake: When Zero and Mr. Gustav are discussing things in the courtyard right after Mr. Gustav escapes from through the sewer system, Zero's bag strap switches between across his chest and hanging by his side in different shots.
Factual error: The concierge in 1968 rushes to help a guest who is choking. The scene depicts him performing the Heimlich Maneuver. It was not introduced until the 1980's.
Continuity mistake: After Mr. Gustave and the other inmates eat the Mendl's pastry, while discussing an escape plan, one of the inmates has the Mendl's box held close to him. The condition of the box, the position of the lid of the box, and the position of the ribbon on the box changes numerous times between shots. (00:43:03 - 00:45:10)
Factual error: In the scene where Jeff Goldblum collects his dead Persian cat from the coat check girl, the cat appears to be bagged in a plastic bag. Plastic bags were not yet in use at the time this part of the story is set in (the 1930s).
Suggested correction: In none of the shots in the scene does the bag appear to be made of plastic.
