The Creature Walks Among Us (1956)

The 3rd film in the Creature From the Black Lagoon trilogy, after Revenge of the Creature (55). This goes into a different direction as the Creature sheds some of its fish-like outer appearance after a fire and begins to look a bit more like a human, and with human lungs. The Creature, therefore, can longer live in the waters, lending a depressing tone to the overall film.
