Buffy the Vampire Slayer (1992)

Continuity: When Buffy is out shopping for her dress and Pike is on his bike beside her, they stop to talk and have an argument. Buffy walks off and Pike turns his bike around to drive off, but as he does this, his bike suddenly moves a few feet away from the wall he was right next to in the previous shot.

Continuity: When the vampire is on the hood of Pike's car, his head is just barely on the windshield. However, in the next shot from Pike's view, the vamp's head is covering the entire windshield. This happens several times.

Continuity: After Pike has crashed his van and he and Buffy are fighting the vampires, Pike gets body slammed by a vampire that's wearing a black hat. The vampire straightens up to face Buffy and the hat is suddenly gone.

In chapter 18 of the DVD when Buffy is cheering at the basketball game and Grueller (now a vampire) shows up we see him growling at a player from the other team. The player then tells him "Here, take it" and hands him the ball. The player from the other team (in the red) is Ben Affleck, pre-stardom.

Seth Green is the only person who appeared in both the "Buffy" movie and the TV series. Although his big scene ended up on the cutting room floor, you can see him in vamp-face on the back of the movie box.

Buffy's surname is never mentioned in the film. It didn't become "Summers" until the TV series aired.
