The Knickerbocker Buckaroo  The Knickerbocker Buckaroo was a 1919 American silent Western/romantic comedy film directed by Albert Parker and starring Douglas Fairbanks, who also wrote (under the pseudonym Elton Thomas) and produced the film. "The Knickerbocker Buckaroo" is now considered lost. Fairbanks plays a hedonistic New York City aristocrat who tries to change his selfish ways by heading to Sonora, Texas to carry out a campaign of altruism. Along the way, he is mistaken for a Mexican bandit and is pursued by a corrupt sheriff who is in pursuit of the bandit's hidden fortune. "The Knickerbocker Buckaroo" was Fairbanks' last film under his contract with Paramount Pictures. After this production, he worked exclusively at United Artists, a company he co-founded in 1919 with Mary Pickford, Charles Chaplin, and D. W. Griffith.
