History remembers early 20th-century academic William Marston (Luke Evans) as developing the forerunner of the lie detector, as well as being the writer who co-created Wonder Woman. Less spoken about, however, was the polyamorous bond that arose between himself, his wife and collaborator Elizabeth (Rebecca Hall), and their student research assistant Olive Byrne (Bella Heathcote). Their controversial union, and it's influence upon his enduring pop culture contribution, is tellingly explored in this drama; Oliver Platt, Connie Britton, JJ Feild co-star. 108 min. Widescreen; Soundtrack: English.
