The High Sign is a 1921 American short comedy film starring comedian Buster Keaton. It was written and directed by Keaton and Edward F. Cline. The runtime is 21 minutes. Although One Week (1920) was the first of Keaton's independent shorts to be released, The High Sign was the first one to be produced. Disappointed with the result, Keaton shelved the film. It was not until a year later, when he broke his ankle and delayed the completion of The Haunted House (1921), that the film was released.
