Sleazy sword-and-sorcery fantasy as only Roger Corman can produce it, "Sorceress" is good fun provided that you're not too demanding. It delivers a generous amount of amusement and fun, especially when it comes to the ridiculous dialogue, and its delivery. For the most part, it doesn't do that much to stand out from the pack of other, similar films during this time. But that all changes when it gets to the climax, a full-on assault of cheese and spectacle, complete with light shows and otherworldly creatures.
A large part of the charm, of course, lies in the casting of luscious twin sisters Leigh and Lynette Harris, playing warrior women Mira and Mara. It seems that one of them needs to be sacrificed by power-hungry villain Traigon (snarling and hammy Roberto Ballesteros). They take the fight to him, aided by such characters as the hunky young Erlick (Roberto Nelson) and the proud Valdar (Bruno Rey), a guy who wouldn't look out of place in a Lord of the Rings feature.
That's really all you need to know, so you can discover the silly pleasures of this lowbrow feature for yourself. John Carl Buechler handles the creature duties, creating a likable "goat man" sort of character as well as a variety of ape-like beasts. The music is liberally borrowed from the earlier New World productions "Battle Beyond the Stars" and "Humanoids from the Deep". The action scenes are basically decent. The Harris sisters aren't exactly very good actresses, but this viewer can't imagine many fans of this type of thing caring all that much.
The sad postscript is that this turned out to be the final directorial credit for exploitation master Jack Hill ("The Big Doll House", "Coffy", etc.), who had a falling out with Corman over the matter of the editing. In the end, Hill retained a producing credit under his name but the direction was credited to a pseudonymous "Brian Stuart" (the names of Cormans' sons).
If you like fantasy features to be on the cheesy, sleazy, low budget side, watching this will be a no-brainer.
