Van Cleef is such a loon in this! I liked his loathesome despicable ways though. Peter Graves goody two shoes and his great ending message:
"He learned to late...by not watching Biography."
Well, it's not that. But do watch for his great last line!
Now Beverly Garland...heh heh.
Word of advice to fellow MSTies. Lee Van Cleef's best role in a MSTied movie is this one. Please, try to control yourself at the shlock series known as Master Ninja where Cleef plays a pudgy American gaijin who's about as credible as Mike Tyson is a candidate for graduating 5th grade.
Remade, a few years later, as Zontar, The Thing From Venus.
