Probably the only reason this title caught your eye is that it stars Mark Gregory from 1990: The Bronx Warriors and Escape from the Bronx. This is his first film after Bronx Warriors and boy is it strange. Both directors of Adam & Eve also co-directed the Blue Lagoon rip-off "Blue Island" a year prior, and this film similarly attempts to capitalize on that as well as 1981's Quest for Fire. Although the Italians did exploit a number of genres in the early 80s, this is an extremely small sub-genre unlike the fantasy and sci-fi rip-offs that were more ubiquitous.
Adam & Eve shares much of the same sensibilities as any other Italian exploitation film of that era. There's some skin, there's some sex, some (minor) gore, a fantasy setting, extremely cheap (but charming) production values.
Surprisingly, this film is really not all that bad. The locations they shot the film are absolutely gorgeous which really set the film apart visually from other genre films of that era. The story of Adam & Eve (from the Bible) is well known and the plot of the film incorporates it surprisingly competently. Once cast out from the Garden, the plot involves encounters with what is best described as a tribe of cavemen and then a violent encounter with savages. Oh, there is the bear scene, and it is gloriously bad...I'm talking worse than Yor. Unfortunately the bear scene is short, but by God, if you like 80s Italian exploitation I guarantee you will never forget it.
I found this little known film on Amazon Prime streaming in a very nice 16:9 print. Personally, I loved the film--but I am a MAJOR fan of Psychotronic film in general and Italian exploitation films from that era in particular. Although most viewers will find films like this laughable and worthy of mocking, I really appreciate them as akin to pulp entertainment. Only folks who share my sensibilities are likely to enjoy this movie--all others should seek out the films it rips off (Blue Lagoon & Quest for Fire).
