1. This Island Earth (1955)
One of the most iconic movie monsters in a horrible, horrible film. The credit for the monster in This Island Earth goes to female horror icon Milicent Patrick (mentioned earlier as the creator of The Creature From The Black Lagoon) and make-up to Bud Westmore. Westmore, in a rage of jealousy, refused to hire Patrick after this film as she was soon to be 'exposed' as the 'The Beauty Who Created the Beast". Mystery Science Theater 3000 would go on to use this as their vehicle for their movie, Mystery Science Theater 3000: The Movie, making the Metaluna Mutant known to film nerds everywhere.
