Cleopatra is a silent film created in 1912 by Helen Gardner and the Helen Gardner Picture Players. The film, in which Gardner stars in the title role, was based on a play written by Victorien Sardou. In a series of elaborately staged tableaux, it depicts Cleopatra (Gardner) and her love affairs, first with handsome fisherman-slave Pharon, then with Marc Antony. The film features lavish sets and costumes and at just over an hour, it was considered fairly lengthy.
