For inclusion in the Final 22 I back, and seek endorsements for this film:
Godzilla Vs The Smog Monster (1971) (Hedora)- A fantastic, innovative and scary film. It's psychedelic, they included animated sequences, amazing set and colors, use of jazz and acid rock, where they mix jazz in with the spoken parts, including rather bizarre things, like the eggs of Monster. It's the first film to attack the issue of pollution, at the same time it's a metaphor for the evil/neglect of mankind.
The horror scenes include a coastal giant sludge tadpole menacing a child's father, and then the child slicing it with his knife. In a nightclub, slug from monster pours down the steps, like the blob (the ending of the scene with the slug covered cat meowing is classic!). The Smog Monster flies over a children camp exercising, releases it's smog on them, and they're left as smoking skeletons (child's film?). The "flower children" teens are partying at night when a GIGANTIC Hedora walks up, even towering over Godzilla (genius). A true period piece.
If you haven't seen Godzilla Vs The Smog Monster, you are missing an artistic film treat! A truly special film. I invite you to toke up, and follow it up with the Yellow Submarine. ;)
