The release of Michael Eisner's memoir about summer camp, called "Camp," has been delayed. Eisner's people say it's because he's too busy to promote it, but a "source close to Eisner" says that wasn't exactly the reason. "The manuscript he turned in was really boring," says the source. "He got into a big fight with [the book's publisher] Warner [Books]. It was so mediocre they wanted him to either have a ghostwriter or a co-author/editor." But a subsequent version written with HBO producer Aaron Cohen was said to be lame, too. It "wasn't marketable at all. It was supposed to be more autobiographical, but it was just all about sending your kids to camp. And who wants their kids to turn out like Michael Eisner? It was just a dumb idea." (Page Six)
