- The show's cast had no idea who "Gossip Girl" was all along until they taped the final epeisode. "The actors were really excited and surprised," Savage told E!. "Everyone has had many theories over the years. I think they liked it."

- There may be a "Gossip Girl" movie in the future a' la "Sex *& The City." "It's funny we've never talked about [a movie] seriously until the show was actually ending," Savage revealed. "We've never had any legitimate conversations about doing a movie until we were saying goodbye. Then we said, 'We'll do a movie, Broadway show or reunion show, right?' Even though we are likely to see each other again it's not like we'll all be working together again, so that's where the fantasy starts."
