The High Sign is a 1921 two-reel silent comedy film starring Buster Keaton, and written and directed by Keaton and Edward F. Cline. Its runtime is 21 minutes. Although One Week (1920) was Keaton's first independent film short released, The High Sign was the first one made. Disappointed with the result, Keaton shelved it and the film was not released until the following year. The title refers to the secret hand signal used by the film's underworld gang.
