xXx: Return of Xander Cage
The last forty minutes of the movie do come together in a pretty diverting way.
In the good old days when Roger Corman was producing about two dozen exploitation movies a year for American-International, he had this interesting way of getting the most for his money. He'd go through all the current acting contracts to see who still owed the company a few days of work. And then if, say, Boris Karloff was still on the books for four days, Corman would commission a horror movie that could be about anything. There was only one requirement: The script had to include four shooting days with Karloff. No more.
"The Deathmaster," a vampire movie that has moved into neighborhood theaters under cover of darkness (naturally) looks like two Corman specials that ran into one another. Judging by the internal evidence, I'd say the producers were into Robert Quarry for about two weeks of work. They also must have had a batch of unexpired contracts with a team of unemployed beach-party extras. How else to explain the most schizo horror movie since..."Schizo"?
Quarry is an old hand at the vampire game by now. The two superstars of the horror genre are Christopher Lee and Peter Cushing, but Quarry has been moving up fast in the last year or two. He was the star of "Count Yorga, Vampire," a fairly good movie, and of "The Return of Count Yorga," which was not bad as these things go.
Quarry knows all the tricks by now. He can even do this thing with his face so you can't tell he's wearing his false vampire fangs. That's important because it maintains the element of surprise. Vampire movies all have one thing in common: The people you think you can trust - your best friends - turn out to be vampires at the crucial moment. They've already been bitten.
