Nina Hartley's Guide to Strap-On Sex Cast: Nina Hartley, Mika Tan, TJ Hart, Christian (aka Christian X). Director: Ernest Greene Videographer: Ralph Parfait Production dates: 8/22/058/24/05 (opening statement), 2/13/06 (box) Length: 89 min. Extras: A 21-min. behind-the-scenes featurette, a 17-min. interview with Nina Hartley, a 14-min. bonus scene from Fleshbacks, 13 min. of trailers (Carmen & Austyn, Tell Me What You Want #4, The More the Merrier, The Contractor, Hair to Stay, Latin Fantasies), and a 4-min. slide show. Audiovisual quality: The camerawork is professional, with smart angles and no focus problems. The lighting is also good. The performers are visually identified one-by-one in the opening creditsa nice touch that shows some extra care. Most dialog is easy to hear and understand. Off-camera directions are also audible in a couple of places, which is my biggest criticism of the technical aspects of this production.
