Those Awful Hats is a 1909 American short comedy film directed by D.W. Griffith. It takes place in a small, crowded movie theatre, where the patrons are perpetually distracted by people primarily women wearing large, ostentatious hats that obstruct everyone elses views of the screen. The film ends with a title card reading, Ladies Will Please Remove Their Hats. A print of the film survives in the film archive of the Library of Congress.
