CHAMPIONS OF JUSTICE is definately the top Mexican Wrestling films with SANTO VS THE VAMPIRE WOMEN close behind. Though they are a bit different in tone and b/w in stead of color.

"The Champions of Justice" would be my choice as the "pick of the litter" as well. It is just incredible. You watch it and cannot fathom why someone would put a film together like this, but it all makes sense - in a luchadores vs. super midgets way. Why wouldn't the wrestlers and super midgets suddenly battle it out in an empty field? Why wouldn't Black Hand freeze all the Miss Mexico contestants, then have them loaded on a plane? Why wouldn't there be evil scuba divers in the lake?

That's me, making a dumb mistake - fixed it now. Thanks for the heads up.
