Keaton, 64, will play the title character, a powerful and greatly feared Hollywood blogger, in the half-hour comedy. Page, 23, will costar as a creative assistant named Carolyn who's torn between following the corporate culture of her studio and following Tilda, who has a great interest in her.

Page will next be seen in this summer's Inception and Keaton will appear on the big screen in Morning Glory, due out this fall.
