There are tons of superhero origin stories, but few like Professor Marston and the Wonder Women. This upcoming biopic, which premieres later this fall, doesn’t explain where Wonder Woman got her incredible powers or her magic lasso. (You can watch Wonder Woman for that.) Instead, it explores the unique man who created Wonder Woman, William Moulton Marston. In addition to his artistic pursuits, Marston also helped invent the modern lie detector, and had what Wikipedia delicately describes as an “extended relationship” with two women: His wife Elizabeth and their lover Olive.

In the film version, Luke Evans plays Marston, Rebeca Hall is Elizabeth, and Bella Heathcote is Olive. In this new round of Professor Marston posters, each character gets their own piece of art. First, here’s Evans’ Marston:

Next, Heathcote’s Olive, rocking a look that evokes a certain superhero:

And finally, Hall’s Elizabeth, who has a piece of rope on her hip. I don’t think she uses it in quite the same way Wonder Woman does.

Here’s the film’s 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, written and directed by Angela Robinson, opens in theaters on October 13.
