Indie film maker Paul Chart (American Perfekt (1997)) was originally signed to write and direct the picture and penned the original script. Chart left the project, however, after a decision was made to shoot the film in 3-D, uncomfortable with the possibility it would become more 'theme park ride' than the epic action-adventure film he envisioned. The Jules Verne novel was apparently one of his favorite pieces of literature. Chart was ultimately replaced with effects specialist Eric Brevig and the script was heavily retooled to emphasize the new 3-D format.
When Trevor opens the box of stuff belonging to his lost brother, he pulls out an odd wooden item, declares that he doesn't know what it is, and sets it aside. The item is a Holmes Stereoscope, a device designed in 1861 by the American physician and writer, Oliver Wendell Holmes, for the viewing of so-called "stereocards". A stereocard is like a postcard which has a Left-view and Right-view photograph mounted alongside one another. When viewed through this stereoscope, the photographs are merged into one 3-D image (which was later adopted for the ViewMaster viewers and cards). The Holmes Stereoscope was a great source of entertainment in the Victorian era. It was, in a sense, the Home Entertainment Centre of its day, as it transported its users to exotic places all over the world. People bought packs of stereocards for their entertainment - in much the same way as we buy DVDs today! (Thus, a character in a 3-D movie having no idea what a stereoscope is, makes for a cute little 3-D in-joke...)
The character name "Maxwell Anderson" (the late brother of Brendan Fraser's character) is an in-joke reference to the famous American playwright of that name, many of whose works have been filmed.
