Transcript for 'Star Wars: The Force Awakens' Premieres Amid Heavy Secrecy
Let's talk about "Star wars" again but so excited. It is finally here, the "Star wars" world premiere, Hollywood heavyweights out in force last night. For "The force awakens." Among them ABC's nick watt there for all the excitement. Good morning to you, nick. Reporter: Good morning, Lara. Well, the movie played just a few hours ago right here in the famous tcl Chinese theater in the heart of Hollywood. Part of the reason for all this excitement and hype is the unprecedented secrecy that surrounded this movie. The trailers were purposefully cryptic. Information like a new hero rey's last name very intentionally withheld. The reason we keep it a secret so people could enjoy the thing. To watch it and not know what happens is amazing. Reporter: You die in this film? Possibly. It's hard for me to talk. Keeping my mouth shut is easy. Really enjoyed the secrecy. Reporter: Why? It's been fun. It's like a power trip. Reporter: Luke, our returning hero absent from the posters, why? I want to see mark Hamill. We've been devoid of mark Hamill. I'm afraid to talk about 7 because I'll leak things. I'm so paranoid. There was no secrecy like this the first go-around. Reporter: There wasn't social media for the first but "Star wars" fans don't want to know. This poster hung on set. One of the things that is most gratifying when people say thank you for not ruining the story for them. Camera, action. Reporter: Rumors of a no-fly zone over the studio, fake scripts for auditions and -- did mark Hamill really have to wear a cape going between his trailer and the soundstage? Mark just likes to wear capes. I've seen this movie ten times so what I have wanted more than anything is let it all out. Even the press we talked to seem to be totally on board. Reporter: Even Carrie fisher kept quiet. I have no filter, boundaries, nothing so I could get in trouble and didn't because people didn't answer specific questions. Reporter: Because it's easy to get sidetracked with her. ? Da, da, da, ? ? Now, age from mark Hamill himself. If you see this movie keep the secrets to yourself in respect of the people who come after you. Guy, that's Luke skywalker to you with your fancy screening in New York later, talking to you. Yes. Under orders. Will Carrie fisher be there? Can she be on every red carpet? I know. Are you jealous of nick. I had my time. I can share her with the world. She'll make time for everything. Amazing like that. Some of the stars that were at the premiere tweeted. Shonda rhimes, "Grey's anatomy" tweeted holily blank, that "Star wars: The force awakens" is so good in the best old-school way and our friend rob Lowe said he, quote, cried like a baby and whooped like a teen. Wow. So really great tweets out there and the rest of us can find out all about those secrets and don't share them, please, on Thursday when the movie opens in 4100 theaters.
