Buffalo Bill (1983)

Bill Bittinger is the egotistical host of a local daytime talk show on WBFL in Buffalo, New York. He's unhappy at being a big fish in a small pond, but unable to break into the big leagues. He makes life miserable for his crew and guests, and especially his station manager Karl Shub, who is constantly dodging lawsuits resulting from Bill's behavior. The one person Bill is unable to bully is his director and on/off lover, Jo Jo White.
