An issue of the magazine "Fangoria" can be seen in the car's trunk.
That beat-up Olds that goes through time with Ash belongs to director Sam Raimi. He included it in most of his early movies, each time more banged up than the last. The items in the trunk of the Olds are not product placements; they're what Sam Raimi actually had in his trunk.
Ted Raimi plays the S-Mart store clerk at the end of the movie.
Movie was originally given a NC-17 rating.
Credits Fun:
In the opening credits, Bruce Campbell vs. Army of Darkness instead of "in".
