The Oz the Great and Powerful director admitted that he is excited about Fede Alvarez's interpretation of the film, describing it as "gut-wrenching" and "intense".
He told MTV: "Fede Alvarez has really made a great horror movie. It's scary. The actors are great in it. It's really gut-wrenching, real low-budget and intense."
Evil Dead sees five friends unleash a deadly curse after they open the Book of the Dead while holidaying at a remote forest cabin. Raimi is producing the remake with original trilogy star Bruce Campbell and Rob Tapert.
The new version will not feature series protagonist Ash Williams, a role popularised by Campbell, and will instead feature a female lead played by Jane Levy.
The Evil Dead is scheduled for release in 2013.
