According to reports in the press, the film used 70,000 gallons (equivalent to 264,978.82 liters) of fake blood. In an interview, Fede Alvarez said they used 50,000 gallons (189,270.59 liters) for the final scene alone. This is compared to the 200-300 gallons (757.08-1,135.62 liters) used in the original.
Although he has a background in CGI, director Fede Alvarez chose to go with practical effects for the film's visuals, mainly out of tribute to what Sam Raimi achieved on a very limited budget back in 1980.
95% of the remake was shot in chronological order. This was done because a lot of the film takes place in a controlled environment and the level of blood and violence gets worse and worse as the film progresses. By shooting in order, the filmmakers could throw blood on the walls and not worry it would mess up another shot where it needed to be clean.
When producer Rob Tapert suggested the possibility of an 'Evil Dead' remake to Sam Raimi and Bruce Campbell, Raimi responded the most favorably, whereas Campbell was the least enthusiastic of the three. Raimi thought that Evil Dead (1981) was exactly the sort of film that could be successfully updated and re-imagined by a new generation of filmmakers, while Campbell was not happy to pass on his iconic role of Ash. He relented when he heard that the film would feature a new set of characters, and the role of Ash would not be re-cast.
This film was originally rated NC-17 until it was toned down to an R rating. According to the director, he and Sam Raimi were always willing to keep the NC-17 rating since the original film has it; however, the studio required that it have an R rating in order to have a wide release.
