When Ash calls Wiseman Joe "spinach chin," it is a reference to the 1949 Three Stooges short "Malice in the Palace." In it, Moe calls a man with a long beard "spinach chin."
An issue of the magazine "Fangoria" can be seen in the car's trunk.
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.
As various missiles such as catapult loads and arrows fly through the air, we see their targets from the missile's viewpoint, a type of shot that director Sam Raimi uses quite a bit.
Credits Fun:
In the opening credits, Bruce Campbell vs. Army of Darkness instead of "in".
