Matt Damon is scheduled to make a return appearance on NBC's 30 Rock Thursday in a telecast that will air live on both the East and West Coast, according to Entertainment Weekly. The episode will be broadcast from NBC's Saturday Night Live stage at 30 Rockefeller Plaza, familiar territory for 30 Rock exec producer/co-writer/co-star Tina Fey. The show will first air in the Eastern and Central time zones at 8 30 p.m.; the cast will then return at 11 30 p.m. for a repeat of the episode to the West. Fey told TV Guide Network. "It's super exciting. ... We're going to do two live shows, so they'll be a little different. Hopefully, people will tweet the differences."
