Dr. William Barton, played by Jeff Morrow, is a character in the film The Creature Walks Among Us
Following the Gill-Man's escape from Ocean Harbor Oceanarium in Florida, a team of scientists led by the deranged and cold-hearted Dr. William Barton board the Vagabondia III to capture the creature in the Everglades. Barton is mentally unstable and apparently an abusive husband to his wife Marcia, as he becomes very jealous and paranoid when Marcia is with other men. Their guide Jed Grant makes numerous passes on Marcia (which she constantly rebuffs), with Barton becoming paranoid about the two.
When he is eventually captured, the Gill-man is badly burned in a fire leading to a surgical transformation performed by Barton, Tom and their colleagues Dr. Borg and Dr. Johnson.
Barton ruins the plans when, in a murderous rage, he kills Jed, jealous that he had made romantic advances towards his wife. Realizing what he has done, Barton then tries to put the blame on the Gill-man. The Gill-man, witnessing the killing, and apparently realizing that he is being blamed for the murder, goes on a rampage. After ripping down the confining electric fence, he kills Barton and then slowly walks back to the sea. He is last seen on a beach, advancing towards the ocean.
