Burning Bright is a 1950 novella by John Steinbeck written as an experiment with producing a play in novel format.
 Rather than providing only the dialogue and brief stage directions as would be expected in a play, Steinbeck fleshes out the scenes with details of both the characters and the environment.
 The intention was to allow the play to be read by the non-theatrical reader while still allowing the dialogue to be lifted and performed with little adaptation by acting companies.
 While Steinbeck could see that providing little information in the way of physical description or stage direction allowed the director and actors greater freedom and scope for imaginative interpretation, he weighed this against the benefit of making the players aware of the author's intent and making the play accessible to the general reader.
Winchester '73 is a 1950 American Western film directed by Anthony Mann starring James Stewart, Shelley Winters, Dan Duryea and Stephen McNally.
 Written by Borden Chase and Robert L. Richards, the film is about the journey of a prized rifle from one ill-fated owner to another and a cowboy's search for a murderous fugitive.
 The movie features early film performances by Rock Hudson as an American Indian, Tony Curtis, and James Best.
 The film received a Writers Guild of America Award nomination for Best Written American Western.
 This is the first Western film collaboration between Anthony Mann and James Stewart.
 It was filmed in black and white.
Apes of Wrath is a 1959 animated short featuring Bugs Bunny.

 The title is a parody of John Steinbeck's novel "The Grapes of Wrath".
Jane Darwell (born Patti Woodard, October 15, 1879 – August 13, 1967) was an American actress of stage, film, and television.
 With appearances in more than one hundred major motion pictures spanning half a century, Darwell is perhaps best-remembered for her portrayal of the matriarch and leader of the Joad family in the film adaptation of John Steinbeck's "The Grapes of Wrath", for which she received the Academy Award for Best Supporting Actress, and her role as the Bird Woman in Disney's musical family film, "Mary Poppins".
 Darwell has a star on the Hollywood Walk of Fame.
The John Steinbeck House at 16250 Greenwood Lane in Monte Sereno, California, was the home of author John Steinbeck from 1936 to 1938.
 The house was built in 1936 for Steinbeck and his wife, Carol.
 While living in the house, Steinbeck wrote "The Grapes of Wrath" and completed "Of Mice and Men".
 The Steinbecks added a guest house to the property after the house's completion; renowned actors, literary agents, and friends of the Steinbecks stayed in the guest house while visiting the couple.
 In 1938, the Steinbecks left the house, as they felt that its location was no longer as secluded as it had been two years earlier.
Dorris Estelle Bowdon (December 27, 1914 – August 9, 2005) was an American actress, best known for her role as "Rosasharn" in the film adaptation of John Steinbeck's novel "The Grapes of Wrath", starring Henry Fonda.
To a God Unknown is a novel by John Steinbeck, first published in 1933.
 The book was Steinbeck's third novel (after his unsuccessful "Cup of Gold").
 Steinbeck found "To a God Unknown" extremely difficult to write; taking him roughly five years to complete , the novella proved more time-consuming than either "East of Eden" or "The Grapes of Wrath", Steinbeck's longest novels.
