Continuity mistake: When the survivors of the sunken ship are floating in the life raft, Geig makes a comment while observing the cloudless night sky: "look, there goes Shepherd..."(something to that effect, in reference to the recent launch of Allen Shepherd in the first Mercury manned-space flight). In actuality, Shepherd's flight was a day launch and a sub-orbital flight lasting only few minutes. He never achieved orbit and therefore would not be visible travelling in the night sky.
Continuity mistake: At the end of the movie when Sandra Bullock character is in the hospital and the nurse revealed to her that Carl Lee was innocent, look carefully at the TV. You can see Jake, Harry Rex and Lucent standing outside the courthouse, but in the very next scene they haven't even left the courtroom.
Continuity mistake: When the kids take Mr. Roth's car, the lights inside the car turns on. When it cuts, the lights are off.
Continuity mistake: When Marty first brings home Shiloh and his mother asks him to hand his dirty shirt to her, as she hands him a clean one, the two exchange shirts twice. They first exchange shirts on a shot over Marty's shoulder, then they cut to over his mom's shoulder and the same exchange happens again. (00:09:15)

Continuity mistake: At the end, when Lisa goes to Lewis's apartment, watch the apartment door when Louis's sister leaves. In one shot, she's leaving and pulling the door closed behind her. Cut, and the door is wide open, with Christian Slater resting his hand on it. Cut again, and the sister is pulling it closed again.
Continuity mistake: Although Corky's apartment is up a long flight of stairs (we see this in all of the establishing shots, as well as the scene where the cast comes to beg him to return to the show), during the scene where he is "wrasslin'" with "the Muse of Dance," the view out the windows is decidedly street-level.
Continuity mistake: When Lewis Scott is told to get into the finals game he is shown unzipping his jacket twice.
Continuity mistake: When the industrial plant explodes at the end of the film, as Peyton and Angela/Jenny escape, in the wide shots you can see the flames are so big, that they actually set the actors on fire. However, in closer shots, not only are the actors not on fire, but the explosions are much smaller.
Continuity mistake: When David goes into the Dodson Hotel to look for Eddie, the glass door he enters through is completely normal. When he runs out chasing Eddie, he goes out the same entrance and this time the right glass door has a huge hole and is shattered. (00:47:40 - 00:49:35)
Continuity mistake: Otter Bob holds out a bottle of liquor at Isaiah after he kills a bear. In the close-up, Bob is holding the bottle by the neck. In the wide shot, he's holding it by the body.
Continuity mistake: When Chance is sitting in the road singing "I left my heart in San Francisco", the road goes from being wet to dry depending on which angle we see it from.
Continuity mistake: In the scene where Faye and T.B. Player burst into the appliance store to announce the song was on the radio, watch the blue car behind them. It moves forward twice, depending on the camera shot.

Continuity mistake: During David Leary's writing class session, Kirby's pen on his table disappears.
Continuity mistake: Bullet approaches the Jaguar with the two rich kids. He is leaning against the roof of the car, but in the close-up where he spits through the half opened window, he's leaning against the glass instead. (00:05:25)
Continuity mistake: When Janice and Guy are lying on the stairs of his loft apartment one of her shoes falls off. In the next shot it's back on her foot.
Continuity mistake: When Alex is walking around nude in just high heels watch carefully. They seem to come and go during the gun battle.
