It may be a bit heavy for some on a Friday, but the newest trailer for Ira Sachs's movie, Keep the Lights On, is available. It shows more of the sexiness--and sadness--that is inherent in this meditation on male-male relationships. As actor Zachary Booth recently explained in an interview, ""I love that it starts with that one-night stand, meeting on the phone line. Even with dating websites there's this shame about how you met: Did you meet in the traditional way?" Watch the trailer and you'll get a little more sense of what he means. The film opens September 7 in select theaters.
