The Bat Woman

Basically just a Santo movie with a female wrestler in the lead nipping like Santo in a sports car about the glamorous backdrop of Acapulco without ever attracting the attention of traffic cops or the public. Currently dropping in is the diabolical Dr Eric Williams (what kind of name is that for a mad scientist, even if he does have an assistant called Igor?), who travels the world in a yacht called Reptilicus harvesting wrestlers to provide components for his prototype fish-man Pisces (who rewards his master by putting more effort into clobbering Williams' goons than fighting The Batwoman).

Crime-fighting heroine Gloria is supposedly a millionairess who moonlights as the masked superheroine The Batwoman; keeping herself in trim when not fighting bad guys as a pro woman wrestler. (The bodysuit and trunks she wears to wrestle being far more becoming of a superheroine than the beach party bikini and cape she adopts a couple of times in the movie - and for the poster- as The Batwoman.) Like Yvonne Craig in the TV series, Maura Monti is far tastier without that stupid cowl covering her hair; and in the film's best (and probably most expensive) sequence she does battle underwater with Pisces wearing just a one-piece, after which Dr.Williams and Igor both get a good look at her without her mask without anyone being remotely concerned.
