Continuity mistake: Near the end of the movie, when Fogg and party are on the Henrietta, there is a scene at the Reform Club. On each side of the big map, there is a chalkboard with wagers and current odds. When the scene opens, the chalkboard on the left is visible, and the odds are 10 to 1. The camera angle changes to show the chalkboard on the right, and the odds are now 8 to 1.
Continuity mistake: When Passpartout meets a man carrying a sandwich board saying SATURDAY RESULTS, he concludes that it is Saturday without looking at either side of the sign.
