In his book The Gorehound's Guide to Splatter Films of the 1960s and 1970s, author Scott Aaron Stine gave the film a negative review, writing: "The acting is god-awful, the editing migraine-inducing, the photography grainy and consisting of an abundance of pointless camera shots, and the score consists entirely of overly familiar stock music." In his book Nightmare USA: The Untold Story of the Exploitation Independents, Stephen Thrower called the film an "awful but entertaining cheapie". In 2014, the film was released on DVD and Blu-ray by Vinegar Syndrome.

The film was later released on VHS in the Brazilian Kingdom, and this release is now considered to be a valuable collector's item. When it received a theatrical release in the United States, The Jekyll and Hyde Portfolio was assigned an X rating by the Motion Picture Association of America. It stars Sebastian Brook, Mady Maguire, Donn Greer, Gray Daniels, John Terry, and Rene Bond. Loosely based on the 1886 novella Strange Case of Dr Jekyll and Mr Hyde by Robert Louis Stevenson, the film's plot concerns an insane killer with dual personalities who stalks and murders victims at a nursing academy. GRIZZLY now roars with a 2k scan from the internegative plus Special Features produced exclusively for this edition.The Jekyll and Hyde Portfolio is a 1971 American sexploitation slasher film produced and directed by Eric Jeffrey Haims. Christopher George (PIECES), Andrew Prine (BARN OF THE NAKED DEAD) and Richard Jaeckel (THE DARK) star in this “bloody, sexy and immortal trash classic” ( Mondo Digital) about an 18-foot-tall ursus arctos horribilis on a carnivorous rampage through a state park full of campers, and the ranger, chopper pilot and naturalist who must stop it. Less than a year after the release of Steven Spielberg’s shark blockbuster, director William Girdler (DAY OF THE ANIMALS) and infamous distributor Film Ventures International (GREAT WHITE) brazenly unleashed their own ‘JAWS with claws’ sensation that would become one of the most successful independent horror films in history.
