The Flubs of Jurassic Park. (Thanks danelope.) I didn't read the whole list, but this one's my favorite so far because it exemplifies the effort-in-all-the-wrong-places way the film is built (and makes it so deserving of a flub list like this one):

... Nedry is supposedly having a live conversation on his computer screen to a guy at the dock, the Mate.... Glance down to the bottom of that video window. Plain as day, you can see a little progress bar sliding along there, indicating the playback of a recorded video file.

Flub #71 is a great one-frame render error that apparently made it all the way to the DVD; see the list's screenshots.
