Character mistake: Near the end, Iris's doctor attempts to take John's pulse. He has his hand wrapped around John's hand, his fingers nowhere near the top of the wrist, where the artery is; and as he counts the "beats", against his wristwatch, John talks to him and he talks back - when you are counting something, you can not talk at the same time; you lose count every time.
Character mistake: Breaking the news of war to the Sayers, Allnut tells them that the war is involving smaller nations like "Austria, Hungary, Belgium, Spain." Spain was not amongst the participants of WW1. (00:10:00)
Character mistake: At one point Michael J. Fox says he doesn't want to end up in Danbury Correctional, why not? The Federal prison in Danbury CT would be a dream come true since he would be the only male inmate, as it became all-female in 1993.
Character mistake: Corie goes into the empty bedroom and says "The bed is six feet long" as she measures it out with her feet "and the room is five and a half feet, and I'm in big trouble." But she only measured the width of the room, not the length.

Character mistake: When Cadence meets the group at the airport and Finch comments "you're reading Descartes", she responds by utterly butchering the line "cogito, ergo sum."

Character mistake: At the beginning of the movie, during "Provincial Life", we see a fat lady trying on a hat in a hat store. The sign over the window, in French, reads "Chapeau" (hat). The correct way to identify that store would have been "Chapeaux" (hats) or "Chapelier" (hatter).
Character mistake: Mr. Phillips told Michael (Danny) that he'd like him to apply for "early admission" to Julliard. Michael was a 17-year-old high school senior and had not yet auditioned for Julliard - the audition is to occur when a student his age is "entering 12th grade in the Fall of the academic year for which he is applying." It was too late to submit an application and an "early admission" was not possible at this point. (01:08:42)
