"Luck," from Michael Mann and David Milch, takes a look at the worlds of horse racing and gambling through a diverse group of characters surrounding a racetrack. It centers on an intelligent, intuitive tough man (Hoffman) who always has been involved with gambling.

Dunn will play the prodigious misanthrope who is the ringmaster of a syndicate of misfits. Nolte would play the trainer of a top racehorse. Condon will play the exercise rider for the horse who is interested in Bug Boy (British actor Payne), an apprentice jockey.

The quartet joins previously cast Hoffman, Dennis Farina and John Ortiz.

Dunn, who next appears in Tony Scott's "Unstoppable," in negotiations to reprise his role as Sam Witwicky in the third "Transformers" film. He is repped by Gersh and Lighthouse.

For Nolte, "Luck" marks the first TV project since his breakthrough role on the 1976 miniseries "Rich Man, Poor Man."

Condon, recently seen in "The Last Station," is repped by ICM and Troy Nankin.

Payne is with Paradigm, U.K.'s ARG and Untitled.
