Annapurna Pictures has followed up its teaser for Professor Marston & The Wonder Women with the biopic's first full trailer. But while the movie is based on the true story behind Wonder Woman's creator, Dr. William Moulton Marston, Diana Prince appears to be nothing more than a looming presence on a more personal story.

Rather than focusing on Wonder Woman's early years, the film tracks the character's inspirations, specifically how the Amazonian's comic books ostensibly were an outlet for the writer to convey his inner feelings on the opposite sex and feminism in general during an open relationship between Marston's wife and lover Olive Byrne. Shifting the focus away from Diana Prince is particularly intriguing given the year that the movie is set to release in 2017, a time when Wonder Woman has never been more popular following Patty Jenkins and Gal Gadot's solo entry in the DCEU series.

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.

Starring Luke Evans, Rebecca Hall, Bella Heathcote and Connie Britton, Professor Marston & The Wonder Women releases theatrically on October 27, 2017.
