Director Sam Raimi shot two different endings. One ending has Ash battling a she-demon in a department store in the present. The alternative ending has Ash imbibing a secret potion that would make him sleep one century for each drop of the potion he drinks. He then goes to a cave to sleep. However, he drank one drop too many and wakes up to find a barren post-apocalyptic landscape. The final shot is Ash screaming in rage at a red sky. The Great Britain video version shows the "potion" ending, and the version shown in U.S. theaters showed the "she-demon" ending.
Movie was originally given a NC-17 rating.
The magic words Ash must use to claim the Book of the Dead are "Klaatu, Barada, Nikto", the same words used to command the robot Gort in The Day the Earth Stood Still.
All European editions of the movie have the original ending (Ash oversleeping and waking up in a destroyed world.) The US "supermarket battle" ending used to be virtually unknown in Europe for a long time.
In the opening credits, Bruce Campbell vs. Army of Darkness instead of "in".
