Truckline Cafe: Truckline Cafe was the title of a 1946 Broadway play written by Maxwell Anderson, directed by Harold Clurman, produced by Elia Kazan, and starring Marlon Brando and Karl Malden.  The short-lived play ran only 13 performances and is best remembered today for the fact that each night Brando would run up and down a flight of stairs prior to an entrance to induce an effectively frenzied demeanor for one of the scenes.  The cast also included David Manners, to whom Brando has attributed much of his subsequent success, and Kevin McCarthy.  The play is noted for Brando's first major appearance on Broadway, during which he garnered attention for an unusually intense performance which presaged his later work on "A Streetcar Named Desire".  "Truckline Cafe" is also notable for being the first collaboration between Brando and Kazan, who later made "A Streetcar Named Desire", "Viva Zapata", and "On the Waterfront" together.  The play also remains notable for being the first time Brando and Malden worked together, prior to co-starring in "A Streetcar Named Desire", "On the Waterfront", and "One Eyed Jacks".
