Like most based-on-a-true-story biographical films, Angela Robinson’s Professor Marston
and the Wonder Women is only loosely connected to actual events. Psychology professor William Moulton Marston (played by Luke Evans in the film) did create the comic book character Wonder Woman, and he did live in a polyamorous relationship with his wife Elizabeth Marston (Rebecca Hall) and their grad student Olive Byrne (Bella Heathcote). Everything else in the movie, though, is up for grabs.
Robinson frames her film around the explicit war against Marston’s life and work. But in spite of complaints about the bondage in the Wonder Woman comics, Marston was never seriously threatened with being fired from the title he created. The comics sold too well, and he was too skilled at defending his work. In spite of the sultry lie detector scenes in the film, the lie detector Marston created never worked, and certainly wasn’t instrumental in getting William, Elizabeth, and Olive to declare their feelings for each other. So far as anyone knows, no neighbor ever wandered into the Marston household and found Marston, Elizabeth, and Olive having kinky costumed sex. William and Elizabeth didn’t subsequently split up with Olive, even temporarily. And as the photos over the closing credits prove, Elizabeth, Olive, and William did not look anything like glamorous movie stars. https://www.theverge.com/2017/10/16/16481692/wonder-woman-professor-marston-homophobia-history-sexuality-real-life-vs-fiction
