Through early November, Landmark's E Street Cinema is hosting weekend midnight screenings of camp and cult classics, including, of course, Rocky Horror Picture Show -- "with live cast Sonic Transducers" -- next weekend, Oct. 8 and Oct. 9. Also on tap in future weeks: Poltergeist, Purple Rain, The Shining and Casablanca. But this weekend brings this John Waters' over-the-top classic Pink Flamingos, the one in which the late, great Divine actually eats dog poop. And then there's that chicken-sex scene. And who can ever forget Edie, the Egg Lady? For obvious reasons, it's NC17. Friday, Oct. 1, and Saturday, Oct. 2, at midnight. Landmark's E Street Cinema, 555 11th St. NW.
