In his new documentary film, The Freedom to Marry, director Eddie Rosenstein (The Greatest Tunnel Ever Built) explores the manner in which same-sex marriage went from being a “preposterous notion” to something widely accepted. The movie makes its Cleveland premiere tonight at 7 at the Cleveland Museum of Art, where it shows again at 7 on Friday night. Tickets are $9, or $7 for CMA members, seniors and students. (Niesel)
