Phantasm IV: Oblivion (1998)

Continuity mistake: When Mike and Jodi are walking through the "deserted" town, supposedly everyone in town has been killed by The Tall Man, when the Tall Man walks down the middle of the street you can see an old lady pushing an empty shopping cart, and a car driving around a corner in the distance.

Continuity mistake: Jennifer's custom Maverick has nice new tires & hubcaps, but after the car flips they are replaced by cheaper, plain ones.

Continuity mistake: When Michael meets Morningside, as he backs away, he backs into an old lady sitting in a chair. Morningside touches her hand, then walks behind the chair and gestures with his right hand towards Michael, yet when the camera goes back to the old lady, she's still holding his right hand.

Trivia: All the flashbacks to the past are actually made up of deleted scenes from the original film.

Trivia: Originally, writer Roger Avary wrote a script entitled "Phantasm 1999AD," which would have been a post-apocalyptic adventure that chronicled the epic final battle between Mike and Reggie, and the Tall Man. Creator Don Coscarelli loved the concept, but wasn't able to secure the funding for it, so this film was made to bridge the gap between films. The project as envisioned never saw the light of day, but a few select elements from it were eventually recycled into the fifth film.

Reggie: Did you hear something?
Michael: It's just the wind. Only the wind.

The Tall Man: Ice cream man, it's all in his head.

The Tall Man: Small Man, your end approaches but it is not yet. Take great care how you play.
