Johnny Knoxville was originally cast as the San Francisco Hobo, but had to bow out due to conflicting schedules.
The French balloon man who calls the main characters insane as they jump into the basket is a cameo appearance by Sir Richard Branson. As well as being the boss of Virgin, he is also famed for his sometimes life-threatening ballooning record attempts.
Director Cameo: [Frank Coraci] as the angry man that Fogg confronts in San Francisco while asking for money.
With a box office loss of around $80 million, this film is considered the biggest independently released flop in film history (it was made by an independent group under Disney).
About 1 hour and 44 minutes into the movie, we see Lord Kelvin in his office playing with the metal spring which we know as the Slinky. As he's playing with it he's humming the song "It's Slinky!" from the old Slinky television commercial.
When Fogg is stuck in San Francisco as a beggar, you can see on the wall behind him a poster advertising the mineral water "Hunyadi Janos". Named after a 15th century Hungarian general, this water had been discovered in 1862 and introduced to the US around the 1880's, whereafter the Hunyadi water became a widely used laxative for the next couple of decades. In fact, you can also note the word "laxative" on the poster.
