The upcoming film tells the story of Harvard psychologist Dr. William Marston (Luke Evans) and how his unconventional relationship with two women (Rebecca Hall and Bella Heathcote) inspired Wonder Woman. Marston’s comic book heroine, which debuted in 1941, was constantly under attack for often featuring sexual undertones and plenty of BDSM that were inappropriate for readers. But he kept the larger secret that he was in a polyamorous relationship. This secret would have ruined his prestigious reputation. The trailer highlights Marston relationship with two women: his wife Elizabeth and one of his students, Olive. The three attempt a polyamorous relationship, all while asking bigger questions about relationships, fidelity, and love. All the while, these two women serve as the creative inspiration for Marston as he develops one of the most iconic characters of the 20th century. Professor Marston & the Wonder Women isn’t arriving in theaters until October, but it’s already gaining a fair amount of controversy due to its depiction of polyamorous relationships. Many people are still uncomfortable with the idea of polyamory, despite the fact that an increasing number of people have admitted to participating in some form of an open relationship. Perhaps this movie’s intimate portrayal will help jumpstart the conversation and smash boundaries just as the recent Wonder Woman film did.
