Santo And Captain America vs Spiderman (1973)

aka's: 3 Dev Adam/The 3 Giants/The Three Mighty Men

This film is considered the holy grail of all superhero flicks. Istanbul is being terrorized by a crime wave, so the police call in American superhero Captain America and Mexican wrestler Santo to put a stop to it. They must battle a crazed Spiderman, who is the mastermind behind all the crimes, and who looks exactly like the U.S. version, except now he is a homicidal maniac who carries a chainsaw and switchblades. He removes his mask only when he wishes to engage in sex. Stan Lee beware! (In Turkish language, with English subtitles).

The picture quality for this film is a bit soft and grainy, but the best currently available anywhere.
