In the weekly column Extra Credit, Charles Bramesco recommends supplemental viewing for moviegoers whose interests have been piqued by a given week’s big new release. 

Comic book fans, polyamory enthusiasts, BDSM fetishists, and history buffs are all in for a treat at the movies this weekend, with the new romance Professor Marston and the Wonder Women inviting a varied demographic. The scandalous life story of William Marston (Luke Evans) — professor of psychology, Wonder Woman creator, inventor of the lie detector, lynchpin in a love-triumvirate with his fiercely intelligent wife (Rebecca Hall) and a beguiling student (Bella Heathcote) — hits some usual beats of the biopic genre, but still refreshes with its nonjudgmental, even celebratory approach to sexuality. Professor Marston, his wife, and their lover indulge in role play and bondage games without guilt, and the camera is content to bask in their glow.

Viewers looking to regain that lovin’ feeling after they see Professor Marston (or looking to capture it if they can’t make it out to the multiplex this weekend) may be interested in some recommendations for further steamy period pieces. Here are five options, and where to find them right now online. Keep a paper fan close at hand, in the event that you get a little hot under the collar:
