Joel Albert McCrea (November 5, 1905 – October 20, 1990) was an American actor whose career spanned almost 5 decades and appearances in over 90 films.
 These films include Alfred Hitchcock's spy film "Foreign Correspondent" (1940), Preston Sturges' comedy classics "Sullivan's Travels" (1940), and "The Palm Beach Story" (1941), the romance film "Bird of Paradise" (1932), the adventure classic "The Most Dangerous Game" (1933), George Stevens' "The More the Merrier" (1941), and the titular character in the western classic "The Virginian" (1946).
 With the exception of the British thriller film "Rough Shoot" (1953), McCrea only appeared in western films from 1946 to his retirement in 1976.
 His most notable western is "Ride the High Country" (1962), in which he starred with Randolph Scott.
Born to the West (reissue title Hell Town) is a 1937 American Western film starring John Wayne, Marsha Hunt, and John Mack Brown.
 Filmed in black and white and based upon a Zane Grey novel, the movie incorporates footage from an earlier and higher budgeted silent version, a common practice of the era.
 The picture features fast chases, gun-fights, unusual poker gambling, and peppy light dialogue for the love interest.
George Randolph Scott (January 23, 1898 – March 2, 1987) was an American film actor whose career spanned from 1928 to 1962.
 As a leading man for all but the first three years of his cinematic career, Scott appeared in a variety of genres, including social dramas, crime dramas, comedies, musicals (albeit in non-singing and non-dancing roles), adventure tales, war films, and a few horror and fantasy films.
 However, his most enduring image is that of the tall-in-the-saddle Western hero.
 Out of his more than 100 film appearances over 60 were in Westerns; thus, "of all the major stars whose name was associated with the Western, Scott most closely identified with it."
Bend of the River is a 1952 American Technicolor Western film directed by Anthony Mann and starring James Stewart, Arthur Kennedy, Julie Adams, and Rock Hudson.
 Based on the 1950 novel "Bend of the Snake" by Bill Gulick, the film is about a tough cowboy who risks his life to deliver confiscated supplies to homesteaders after gold is discovered in the region.
 "Bend of the River" was filmed on location in Sandy River, Mount Hood and Timberline, Oregon.
 This is the second Western film collaboration between Anthony Mann and James Stewart.
South of Heaven, West of Hell is a 2000 American Western film starring Dwight Yoakam, who also co-wrote, directed, and scored the movie.
Gold Raiders is a 1951 comedy Western film starring George O'Brien and The Three Stooges (Moe Howard, Larry Fine and Shemp Howard).
 The picture was O'Brien's last starring role and the only feature film released during Shemp Howard's second tenure with the trio.
Where the Hell's That Gold?
 is a Western film starring Willie Nelson and Jack Elam.
The Bargain is a 1914 American Western film starring William S. Hart.
 It was the first feature film starring Hart, who would go on to become the most popular Western actor of the silent film era.
 In 2010, it was added to the National Film Registry.
The Canadian Spinal Research Organization is a nationally registered charity whose mission is improve the physical quality of life for persons with spinal cord injuries (SCI) and related neurological deficits, as well as reduce the number of spinal cord injuries through awareness and prevention programs.
William Scott Elam, known as Jack Elam (November 13, 1920 – October 20, 2003), was an American film and television actor best known for his numerous roles as villains in Western films and, later in his career, comedies (sometimes spoofing his villainous image).
 His most distinguishing physical quality was his lazy left eye.
 Before his career in acting, he took several jobs in finance and served two years in the United States Navy during World War II.
