The 15th annual Northampton Independent Film Festival presents three films this week: Roman Polanski: Wanted and Desired, an award-winning documentary; Orgasm, Inc. (a still from which is pictured), a documentary that offers an inside look at drug trials for what is dubbed Female Sexual Dysfunction (FSD); and Friends (With Benefits), an illuminating story about the complications that can arise from mixing friendship with romance. The smaller scope of the festival, according to the NIFF website, is preparation for a series of screenings. Nov. 7, 5-11 p.m., The Academy of Music, 274 Main St., Northampton, (413) 584-9032.
