How the Leno/Letterman Super Bowl ad came together

The spot was shot last Tuesday afternoon, under the strictest of secrecy which involved both Mr. Leno and Ms. Winfrey flying in surreptitiously to New York, and arriving incognito at the theater, while Mr. Letterman was in the midst of taping his show for that night. It also involved Jay wearing a disguise: hooded sweatshirt, glasses and faux mustache. If you happened to be on Broadway between 53rd and 54th street last Tuesday about 4:15, you might have seen a man fitting that description slip into the theater by a small entrance under the marquee…

Both guests turned up while Mr. Letterman was on stage doing his show. They were kept in a secret green room until the show was over and the theater was cleared. Then Mr. Leno and Ms. Winfrey went up to the theater balcony where a living room set was fashioned with a faux TV and a couch.

Mr. Letterman arrived a short time later. The two late-night rivals greeted each other warmly, Mr. Burnett said. “It was very friendly, very professional, totally cordial,” he said. “You could tell these were two guys who have known each other for a long time.”
