How bad is it? It's among the worst of both James Bond rip-offs and worst Indiana Jones rip-offs.
Should you see it? It has a baboon driving a tank. Watch it for that.
This is a sequel to "Unmasking the Idol," a bad film in its own right, but this one borrows some of the plot of "They Saved Hitler's Brain" as well! A James Bond type (pocket wire saw, portable SCUBA) and his female assistant and seven henchmen straight out of "The Magnificent Seven"... and a baboon... try to stop South American islanders from resurrecting the frozen body of Hitler. The baboon wears a tux, starts a plane and drives a tank. They end up escaping in a hot air balloon. There's no nudity, but there's plenty of loopy action.
