Revealing mistake: When Scotty tells Dan to test the bus' aerodynamics, the bus passes the same scenery multiple times.
The Big Bus (1976)
1 revealing mistake
Directed by: James Frawley
Starring: Stockard Channing, Rene Auberjonois, John Beck, Joseph Bologna
Continuity mistake: When the bus is brought out of the hangar for its maiden trip, the top of the front of the bus just clears the top of the roof. When it parks outside, the rear section has a glass roof which wouldn't clear the roof without damaging either the bus or the hangar roof.
Kitty Baxter: Dan's a good man, and he's never eaten a whole person in his entire life.
Trivia: Stockard Channing almost drowned during the scene where the bus' kitchen is flooded by the soda machines.
