The Creature Walks Among Us

The Creature Walks Among Us is a movie starring Jeff Morrow, Rex Reason, and Leigh Snowden. A scientist captures the Creature and turns him into an air-breather, only for him to escape and start killing.
Scientists surgically transform the Creature into an air-breather, but being able to live on land is not enough to make him comfortable with humans. Enraged, he turns his wrath on anyone who comes near as he desperately tries to return to the deep-water world where he truly belongs.
