Often considered to be a remake of The Evil Dead (1981); however, this is not accurate. The rights to show scenes from the original could not be obtained to re-cap what happened, so the beginning was remade to explain how Ash got to the cabin, etc.
The recap of The Evil Dead (1981) includes a shot where the "evil force" runs through the cabin and rams into Ash. When this shot was filmed, Bruce Campbell suffered a broken jaw when Sam Raimi (who was operating the camera) crashed into him with a bicycle - or so people were led to believe. This was a story concocted by Sam Raimi and Bruce Campbell as a gag to see how many people would believe it actually happened.
During the scene where the severed head of Linda bites Ash's hand, Bruce Campbell says the single line "work shed". This line was later re-dubbed in post-production due to the quality of the audio, giving it a strange, slightly "disproportionate" sound to the audio. Nine years later, while filming his cameo in Escape from L.A. (1996), the first thing Kurt Russell said to Bruce Campbell on the set was, jokingly, "Say 'work shed'".
The sexy, surly Bobby Joe was inspired by Holly Hunter, who was a housemate of Sam Raimi's in the early 80s, along with Joel Coen and Frances McDormand. One particular incident inspired the character: Hunter was auditioning for a hooker part and was unusually made-up and wearing a sexy, short-skirted outfit. She became angry at Raimi when he somewhat leered at her. Raimi pulled for Hunter to play the part, but the producers wanted someone "sexier".
The trivia item below may give away important plot points.
A glove belonging to the A Nightmare on Elm Street (1984) Freddy Krueger character can be seen hanging above the door of the tool shed when Ash carves his girlfriends head with a chainsaw and when he's looking for the pages in the later cellar scenes. This was in response to the use of The Evil Dead (1981) on a television screen in A Nightmare on Elm Street (1984).
