Ted Raimi plays the S-Mart store clerk at the end of the movie.
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."
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.
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".
