PEG O MY HEART (Metro Studios, 1922), directed by King Vidor, under the supervision of J. Hartley Manners, introduces the legendary theatrical actress Laurette Taylor (1884-1946) to the screen reprising the role she made famous as a poor Irish farm girl who inherits a fortune but would rather have happiness instead. While a bit too old for the character supposedly in her late teens or early twenties, Laurette was tailor made for it.

Annette Kellerman, the Australian swimming star of the early 1900s, made a number of films, most of them in the 1910s, which displayed her athletic skills. Most of these films were underwater fantasies, and this one was no exception. Here, Kellerman is Merilla, a mermaid who is the "Queen of the Sea." Not satisfied with being a mermaid, she wants a mortal human body with an immortal soul. She discovers she can achieve this if she saves four human lives.
