Here's some deep lore:

Penn (and Goudeau) were slated to do a TV show for Sci Fi called "Penn Jillette's Fi-Sci." To quote:
Every show will cover 4 movies. I do a little monologue and then I'll talk about some movie, just kind of sum it up. Then we'll go to tape and I'll have done an interview with a real scientist about the subjects brought up in the movie. I might do a science demo on most shows explaining something we've talked about. I'm hoping to get Richard Dawkins to do "Planet of the Apes" ("Could monkeys really evolve mouths that don't move right when they talk?"), get some NASA boys to do all the travel to Mars movies, you get the idea."
