YMMV / The Adventures of Captain Marvel

• Visual Effects of Awesome:
  • The flying effects were top of the line for a serial made in 1941, and through a combination of wirework, dummies gliding on cables and stuntmen doing cleverly edited acrobatics, it created a visually impressive "flying man" effect for the audience at the time.
  • One especially impressive scene has the Scorpion melting a cave entrance to seal Captain Marvel in a death trap that was achieved by actually melting the film stock to make it appear like solid rock was being transformed into lava.
  • Frank Coghlan Jr (who played Billy Batson) recalled the Transformation Sequence saying "Every time we did that, they ignited flash powder, which was in a trough in front of me, and if the wind was unkind, I'd get the powder flash in my face and lose some eyebrows."
