Although this is Janeane Garofalo's first starring role, Uma Thurman naturally got top billing because she was a much more famous name, even though she only gets half the screen time Garofalo does.
In the scene where Uma Thurman and Janeane Garofalo are in the bookstore, Bob Odenkirk and David Cross are in the background looking at a large shelf of books.
Janeane Garofalo has been quite vocal about how unhappy she was with the film. Initially it was an independent film, but it was turned into a big-studio project when Uma Thurman signed on. Garofalo remarked,"I think it's soft and corny. The soundtrack makes you want to puke. And everybody's dressed in Banana Republic clothing. The original script and intent was very different. It was supposed to be a small-budget independent film, with a lot more complexity to the characters. When it became a studio commercial film, Abby and the guy wind up together at the end." Garofalo has since disowned the film, calling it anti-feminist.
When the car brakes for the bicyclist, the stunt driver locks the rear wheels to make noise and smoke. When he drives off, the rear wheels are still locked.
When is taking photographs of Abby, he switches from a tripod-mounted to a camera to a hand held camera. When he does this, he doesn't change the flash to the new camera (the flash hot shoe is shown to have nothing connected), yet the flash still fires.
The flashes in question are studio flash heads powered from a remote pack. They are fired via a PC sync cord which can be clearly seen attached to the PC sync socket on the left hand side of each body.
