7 Faces of Dr. Lao (1964)

In director George Pal's fantasy:

• Dr. Lao's (Tony Randall) arrival in a western Arizona town with a traveling circus
• the scene of the snake-headed fabled monster, the Medusa (also Randall) turning the disbelieving and shrewish housewife Kate Lindquist (Minerva Urecal) into stone
• the fantastic sequence in which Dr. Lao's pet fish became a large sea serpent (the legendary Loch Ness monster) after a drunken cowboy shot at Lao's fish bowl, until it again became wet and shrunk back to its normal size
