HBO has signed on Tommy Lee Jones and Samuel L. Jackson to star in The Sunset Limited, an adaptation of the Cormac McCarthy play that Jones will direct, according to Variety.

McCarthy adapted his play into a script.

Jackson plays a man who saves another man (Jones) from throwing himself in front of a Harlem subway train. The act begins an exchange of ideologies as the two men from different backgrounds debate the worth of their lives.

Production will begin next month in New Mexico.
