This very enjoyable and excellent film, about early television--which starred the late Peter O'Toole, as well as Joseph Bologna, and Mark Linn-Baker--airs tonight on Turner Classic Movies (at 10:15, Eastern time). The film, from 1982, was directed by Richard Benjamin.
Joseph Bologna plays the Sid Caesar-like star of a weekly network television show; his name, in the film, is King Kaiser. I've always liked how the name not only brings to mind Sid Caesar's name, but Kay Kyser's. Mr. Kyser, whom I've written about often in this space, was also a star in early television (though an even bigger star, indeed, during his radio years).
