When T.S. pulls up to Brandi's house to pick her up for the trip, all the trees have leaves on them and the grass is green. In all other outdoor shots, the leaves have fallen off the trees and the grass is brown.
Brandi tells T.S. that the female contestant for her dad's show had an embolism pop in her head in mid backstroke. Embolisms occurs when an object (usually a clot) migrates from one part of the body (through circulation) and causes a blockage (occlusion) of a blood vessel in another part of the body. There is no popping involved. Brandi is apparently confusing an embolism with an aneurysm (a localized, blood-filled dilation (balloon-like bulge) of a blood vessel caused by disease or weakening of the vessel wall).
In the scene where the cop cars converge on the mall,watch the cop from the car close to the camera. His hat is starting to tilt as he emerges from the car and as he runs it completely comes off his head with what seems to be a white "headband" inside that falls away from the hat and both of these are ignored by that cop and the succeeding ones.
When T.S. is picking Brandi up to go to Florida he has longer hair, but during the rest of the movie his hair is much shorter. This is because the scene was re-shot after the original storyline was changed.
After coming from Miss Ivannah's, T.S. parks close to the mall in a spot between a Honda Accord and a Honda Civic. However, in the next shot, when T.S. and Brodie get out of the car, the station wagon is seen parked farther into the parking spot and between a black pickup and a Ford Taurus. Furthermore, the car is much farther from the mall than it appeared in the previous shot.
Near the end of the film, when Brodie Bruce gives his speech to Rene, a shot of Shannon Hamilton shows that the top and third and fourth from the top buttons are unbuttoned. Then the camera cuts to Brodie, but when they cut back to Hamilton all the buttons are buttoned except the top one.
In the first scene with Brandi and T.S., Brandi has her glasses on until T.S. picks her up. Then they mysteriously show up in her hand. (She took them off in a deleted scene, but not in the released version of the movie.)
Right before Rene breaks up with Brodie, she opens the basement window all the way so that it's touching the ceiling. The window is no longer completely open as she leaves. (In a deleted scene, we see that it keeps sliding shut, but not in the released version of the movie).
Brandi's hair changes length between shots during the game show. It changes right after Brandi says "You don't know when to quit, do you?" It changes back to its earlier, shorter length with the line "He just goes on with his life." (The scene where she says "You don't know when to quit, do you?" was filmed at a later date, accounting for the mistake in hair length.)
When Jay and Silent Bob are running from La Fours, they stumble into the loading docks. When Silent Bob pulls out his grappling hook gun, he isn't wearing any gloves. When he and Jay get pulled up, Silent Bob is wearing black gloves.
When Jay and Silent Bob are being chased by La Fours, they run into a dead end. Silent Bob reaches into his coat and pulls out a vibrator, then throws it away. He pulls out an inflatable doll, and throws it away. Then he pulls the Batman-like gun from his belt, shoots the grapple hook, hugs Jay to him, and they fly up out of reach and view. La Fours arrives at the dead end, but the vibrator and doll are nowhere to be seen.
When Brodie is playing hockey in the beginning of the movie he says he is in the middle of the second period, but the clock in the lower right hand corner of the television is counting down from about 20 seconds.
The 3D picture is not a sailboat but three rows of various 3D objects. From left to right, top row they are: diamond, sphere, diamond, and star. The last item from middle row looks to be a beach ball. And finally the bottom row is a series of four 3-D undulations.
On the first floor, Brodie notices Rene and Shannon going up the escalator (just to go to the elevator). However, when waiting outside the elevator, some camera shots reveal that they are still on the first floor ("1" is shown on a small sign in the elevator entrance way).
After the stink palm incident Mr. Svenning becomes ill and Roddy explains that he came down with a sudden case of diphtheria. Diphtheria is an upper respiratory tract infection and would not cause excessive vomiting.
In the "Truth or Date" game show, Suitor #3 is introduced as a student at Rutgers majoring in Greek Mythology. There is no such major; he could major in the Classics and that would include studying Greek Mythology, as well as several similar classes. Rutgers offers a major in the Arts and Sciences but not specifically the Classics.
The board advertising Ivannah's talents refers to 'rhunestones', a word not to be found in the dictionary. However, rather than a typo it is probably a deliberate melding of 'rhinestone' (a fake diamond) and 'runestone' (a stone with a runic inscription).
