In honor of the partial lunar eclipse tomorrow night, Summit Entertainment and Moviefone are teaming up to host Twilight Night, an evening of free outdoor screenings of the first two Twilight Saga films in 12 major cities, some of which will feature surprise cast appearances! Better arrive early, though—the events are first come, first served! Get all the deets on the official Eclipse site. BONUS: If there's not a Twilight Night near you, watch the action live on at 10 p.m.!
