Everyone knows about Wonder Woman, but how many people know just how fascinating her origin story really is? Soon, lots of folks will know when Angela Robinson’s Professor Marston and the Wonder Women hits theaters this weekend, as much a historical account of the creation of the Wonder Woman comics as it is an examination of her creators and their unconventional sexuality.

Luke Evans, Rebecca Hall, and Bella Heathcote play the trio of lovers responsible for bringing Wonder Woman to life, through their relationships with each other and through Professor Marston’s (Evans) desire to create a mainstream character empowering to women. The film charmed critics at TIFF, including our Matt Singer, who called it “a fascinating and tender companion piece to Patty Jenkins’ Wonder Woman which hit theaters earlier this year. In a way, this is the perfect time for Professor Marston to come out, after we’ve all had a refresher on Diana Prince’s Themiscyran origins.

Here’s the official synopsis:

In a superhero origin tale unlike any other, the film is the incredible true story of what inspired Harvard psychologist Dr. William Moulton Marston to create the iconic Wonder Woman character in the 1940's. While Marston's feminist superhero was criticized by censors for her 'sexual perversity', he was keeping a secret that could have destroyed him. Marston's muses for the Wonder Woman character were his wife Elizabeth Marston and their lover Olive Byrne, two empowered women who defied convention: working with Marston on human behavior research -- while building a hidden life with him that rivaled the greatest of superhero disguises.

Professor Marston and the Wonder Women opens in theaters on October 13.
