Deliberate mistake: When Mr. Roboto is offering Austin a mushroom, the subtitles lead Austin to think Mr. Roboto is asking him to eat some shit, until Foxy reveals more of the subtitles to say "Please eat some shitake mushrooms." The correct spelling for this kind of mushroom is "shiitake." They had to cheat on the spelling in order to make the joke work.
Deliberate mistake: Basil tells Austin he is being sent to Studio 69 located on Eighth Avenue and 69th Street in New York City. However there is no such address. Eighth Avenue ends at 59th Street, after that it becomes Columbus Avenue.
Answer: An original cut featured the opening scene with Heather Graham in it (I'm not sure what happens) - I'm assuming they dropped that idea when they could get hold of all the cameo stars. Hopefully it'll surface on the DVD.
Reportedly she left Austin because he couldn't get over Vanessa.
