The King of Comedy was only a movie. But Jerry Lewis doesn't seem to understand that. He evidently thinks that he found his true calling in King, playing a talk show host. So now he's made five shows as pilots that have been airing in syndication. The first featured Frank Sinatra as a guest. "You know Frank," Jerry says, "he's a pussycat and a sweet man." Beloved of children and little animals, that Frank. Night No. 2 brought Norm Crosby and William Shatner to the stage with Jerry and his co-host, Charlie Callas. Class acts, every one. Jerry loves all his guests and they all love him; the sincerity oozes in 3-D. "You're good," Jerry tells Shatner, "because the creative process is important to you." The man is an artist. To break up the sappy sincerity, you get Jerry putting on oversize dentures and playing spastic. It's something only a Frenchman could love. It's too tacky for Vegas. There's one big difference between the Jerry Lewis Show in real life and in the movie King. In the movie, he had a director and a script to tell him what to say.
