When Ash is possessed of the evil presence and beats up the girl, he throws her on the couch and chuckles evilly (or hornily, same dif). He is stopped from committing further molestation by the sight of that ugly piece of jewelry that he gave to Linda earlier. When the necklace gets a closeup, the chain forms the outline of a skull.

In the last scene, after Ash has traveled back in time, a knight lifts his visor and shouts, "Hail he who has come from the skies to deliver us from the terrors of the Deadites." This knight is Sam Raimi, the director. The knight to his left is his brother Ted Raimi.

The person wearing the Henrietta costume is Sam Raimi's brother Ted Raimi. Ted Raimi can also be seen in Army of Darkness as the S-Mart clerk in the U.S. ending, and in Ash's pep talk to fight the army of the dead.

This film is actually still the center of a massive fan-controversy. The opening scene re-caps the events of the first film, but changes some major details, causing many fans feel this is a "remake" of "The Evil Dead", not a sequel. In fact this film is a sequel, the footage had to be altered for legal reasons, after footage from the first film could not be obtained, and then again for time reasons, because the recap would be too long if it included all the major events from the first film. However, despite director Sam Raimi and actor Bruce Campbell explaining several times that this is a sequel (including in the DVD commentary for the third film), and the fact that the end credits refer to the film as being the sequel to "Evil Dead", some fans still feel it is a remake.

There is a Freddy Kruger glove in the basement just before Ash goes into the pipe section to retrieve the pages, not so much a mistake but an interesting tid-bit.
