Continuity mistake: Hooper wears rimless eyeglasses, with the arms either attached at the upper corners of the lenses or at the sides of the lenses. If this didn't happen between shots within the same scenes, it could be presumed that Hooper has two different pairs of glasses and switches between the two, but they do indeed change between shots, such as when Mrs. Kintner slaps Brody, or even later, on the Orca.

Continuity mistake: At the Zurich sanction when Jonathan kicks the killer out of the window, just before he kicks him, look at the window. This window has two panes of glass that open outward, with the latch in the middle, but a view from the outside shows that it's a single window with one pane of glass in it, not big enough for two panes.

Factual error: Two passengers play a piano/vaudeville routine in the lounge for the officers and passengers. During its initial season (1936) Hindenburg had a lightweight aluminum baby grand piano on board. However, passenger accommodations were expanded over the winter of 1936/37 and the piano was removed. There was no piano aboard Hindenburg on her fatal flight in May 1937.
Continuity mistake: When Doyle arrives at the dock at the beginning of the movie, we see Doyle from behind. A boy with a yellow shirt and a girl with a flower dress pass him on his right side. However, there is a change of shot, and now we see him from the front, and behind him we see the boy and the girl, but instead of being at his right side, they're at his left.
Continuity mistake: When the RV is driving to Amarillo towards the end of the film, the vehicle is coming towards a detour sign and we see a group of road workers, one of which is a bearded man with a cowboy hat and no t-shirt. But when we see a view from the RV going towards the detour sign, the bearded man is seen walking towards his colleagues.
