The ten episodes of Curb Your Enthusiasms fourth season are largely motivated by the improbable premise of Mel Brooks offering Seinfeld creator Larry David the opportunity to star in Brooks smash Broadway musical The Producers. Somehow this setup results in a blood feud between Larry and Ben Stiller (a case of adding injury to insult). Other mishaps during this season include a politically incorrect confrontation with a group of handicapped workers, a world-class crisis involving name tags, a set-to with David Schwimmer over cashews and raisins, an attempt to skirt the traffic laws and to provide medical marijuana for Larrys dad, and the near-death of the best friend of Larrys associate, Jeff (Jeff Garlin). The season comes to a riotous conclusion with a special one-hour episode built around Larrys opening night on Broadway. Events crucial to the outcome include a benighted tryst with The Producers co-star Cady Huffman and the ultimate revelation of Mel Brooks ulterior motives for casting Larry in the first place. Suffice to say that the dialogue sounds awfully familiar in this climactic episode, which also features cameos by Brooks actress wife Anne Bancroft and a certain comic named Jerry Seinfeld ~ All Movie Guide
