Has that super-secret project Jerry Seinfeld and Larry David are working on together been revealed? It sounds the two “Seinfeld” masterminds maybe collaborating on a play.
According to Showbiz411, David let the details slip during a Golden Globes after party. He kept his words short but says he has written a play for Broadway. When asked if Seinfeld would star in it, he answers, “Maybe, we’re talking about it.”
David also reveals he’s writing another season of “Curb Your Enthusiasm,” but it sounds like his primary focus is on the play. Seinfeld first let news of the project, be it the play or not, slip during a Reddit AMA. “All I can do is tell you is that it’s big, huge, gigantic. Even bigger than that Amazon package,” he writes.
