 The soundtrack score was composed by Leonard Bernstein.
 The film was suggested by "Crime on the Waterfront" by Malcolm Johnson, a series of articles published in November–December 1948 in the "New York Sun" which won the 1949 Pulitzer Prize for Local Reporting, but the screenplay by Budd Schulberg is directly based on his own original story.

 The plot follows the relationship of Aurora, a young school teacher, with two men of opposite generations who fall in love with her: Fernando, a middle age republican exile, and Juan, a thirteen-year-old boy who enjoys playing acting in Westerns, and his imitation of Marlon Brando gives the film its title.

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 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.
