Factual error: In the scene where the FBI agents have taken Giovanni Ribisi in for interrogation, one of the FBI agents says at one point "...and I want the whole C:/ Drive backed up on a floppy.", which is pretty hard to do, if not impossible, unless you've got about a 5Mb hard disk drive (depending on compression levels). But later on in the scene where Ribisi is actually doing it, he does it in about 10 seconds...with a 1.44MB floppy.
Factual error: A Series 7 license alone will not allow you to sell securities. You need an Investment Advisor License (Series 63) and a State license (Series 65) as well, or complete the Series 66 exam which is a combination of the two.
