Chris WedgeChris Wedge reports on the commentary that Robin WilliamsRobin Williams performed the scene with Fender and Rodney attempting to get past Tim eight times in eight different accents, including as a Polish valet.
The filmmakers wanted the music score to sound like it was recorded by the "Robot Philharmonic". To that effect, they hired performance artists [?] Blue Man Group, known for performing on musical instruments made from industrial piping and other found objects, to do special percussion effects.
On the "Map of the Stars' Homes" that Fender tries to sell Rodney, the names of the stars are: Jeremy IronsJeremy Irons, Orson Wheels (Orson WellesOrson Welles), Axle Rose ([?] Axl Rose), Britney Gears (Britney SpearsBritney Spears), Farrah Faucet ([?] Farrah Fawcett), and M.C. HammerM.C. Hammer.
A special rendering tool was created specifically to randomly place the pips on every domino in Bigweld's workshop.
The original concept for the film was a 1930s-style screwball comedy with musical numbers.
At one point, a voicebox with a recording of Darth Vader's voice is found. Ewan McGregorEwan McGregor, the voice of Rodney Copperbottom, played a young Obi-wan Kenobi in the StarWarsprequels, the third of which being released in 2005, the same year as this film.
After Rodney is dumped outside Bigweld Industries by the giant magnet, all the metal shavings from the slogan sign stick to his head, just like the old-time Magnetic Face toys.
In the UK Aunt Fanny had to be renamed, as 'fanny' is a common UK slang word for female genitalia, so they renamed her to 'Aunt Fan.'
After Fender steals Rodney Copperbottom's foot, Robin WilliamsRobin Williams delivers the line "Foot don't fail me now" which is similar to the phrase "Feet don't fail me now" made famous by [?] Stepin Fetchit.
