One of the items visible in Ash's trunk is a copy of "Dark Horse Presents Fifth Anniversary Special," originally published in April 1991. This comic includes the very first installment of Frank Miller's 'Sin City.'
Bruce Campbell says that in order to make it appear that the chainsaw was always running, tobacco smoke was pumped through a tube that was slid up his right pant leg, up his shirt, and into the chainsaw.
There are several variants of the three words Ash must say when retrieving the necronomicon. Undoubtedly this arises from differing sound quality, people's hearing, and incorrect subtitling. The words are klaatu, barada, nikto, a reference to the sci-fi movie "The Day the Earth Stood Still".
During the filming of Army Of Darkness the Delta 88 car falling out of the sky was shot two times. During the first attempt, the 25 ton crane lifting the Oldsmobile failed due to mechanical problems and toppled over the edge of a cliff at the quarry location where filming was taking place. Fortunately no injuries occurred as the crane operator dropped from the cab before the crane went over the edge. Days later a larger 80 ton crane was brought in to remove the damaged crane and re-shoot the car drop. In the final edit, elements of the re-shoot as well as footage from the end of Evil Dead 2 were used.
During filming of the climactic sword fight at Arthur's castle, Bruce Campbell suffered a small gash to his face when a decorative pin on his cape cut him during a stunt. He was immediately taken from the Polsa Rosa Ranch location to see a plastic surgeon to assess the damage. At the examination the doctor had to have the actual injury pointed out amid the myriad special effect scars and cuts Ash's character had accumulated during the story. Campbell was treated and returned to set shortly afterward to finish the scene.
When dubbed in Italian, the last words of the movie (Ash says to the girl before kissing) are changed from "hail to the king baby" to the Italian translation of "give me some sugar baby" ("Dammi un po' di zucchero, baby"). These are the same words that Ash says (both in Eng and Ita version) to Sheila before kissing her for the first time.
According to Sam Raimi in the book "The Evil Dead Companion" by Bill Warren, Charles Napier was to play Ash's boss in S-mart, but his role was totally cut. Likewise, Bridget Fonda was scheduled to have more screen time as Linda.
That beat-up Oldsmobile that goes through time with Ash belongs to director Sam Raimi. He included it in most of his early movies, each time more banged up than the last. The items in the trunk of the Olds are not product placements; they're what Raimi actually had in his trunk.
