The How About Project Part 21 (of 26)

Films based on comic books weren't rare before the 80s, especially in Europe, but those based on superheroes were another story. Christopher Reeve didn't appear as Superman until 1978.

Dig deep enough and you'll discover some real gems based on Golden Age and Silver Age heroes, and even villains.

Here are a few that I didn't know existed but would love to see, especially the Captain Marvel serial which was the first ever American comic book superhero to appear on the big screen:

3: Adventures of Captain Marvel (1941 serial)
2: The Wild World of Batwoman (aka She Was a Hippy Vampire) (1966)
1: Danger: Diabolik (1968)
