Frank Powell
Frank Powell (born Francis William Powell, May 8, 1877) was a Canadian-born stage and silent film actor, director, producer, and screenwriter who worked predominantly in the United States. He is also credited with "discovering" Theda Bara and casting her in a starring role in the 1915 release "A Fool There Was". Her performance in that production, under Powell's direction, quickly earned Bara widespread fame as the film industry's most popular evil seductress or on-screen "vamp".
Frank Powell
Frank Powell was born in 1877 in Hamilton, Canada, the child of Elizabeth and Francis Powell. According to the 1920 edition of the "Motion Picture Studio Directory and Trade Journal", he received part of his education in Cleveland, Ohio, although that publication provides no other information about his schooling or reveals whether his interest in theatre began in that city. However, a 1916 notice in the trade paper "Variety" does confirm Powell's close and early connection to Cleveland. In an April 26 news item titled "Frank Powell Resting", the widely read publication announces that the 38-year-old director was traveling to Cleveland, "his boyhood home", for a vacation. What is known about Powell's 12-year stage career is that he worked with playwright Kirke La Shelle and performed in at least two major Broadway productions. In 1904 he performed in the play "Tit for Tat" at the Savoy Theatre, and the next year he both acted in and served as a director for Augustus Thomas's comedy "The Education of Mr. Pipp". He then relocated for several years to England, where he directed productions for actress Ellen Terry before returning to North America. In its October 15, 1915 issue, the "Austin Statesman and Tribune" provides details about the course of Powell's initial stagework with Terry, background that he shared with the newspaper in an interview:Mr. Powell's stage career started as a stage director for the Frohman production "The Education of Mr. Pipp." He went to England with this play [in 1905], and while there attracted the attention of Ellen Terry, who engaged him to produce some of her most famous successes. He remained with Ellen Terry three years when he became interested in the production of great historical spectacular film dramas. In this work his knowledge of the classical drama and of massive stage classics stood him in good stead. He had become a master of types, costumes, architecture and picturesque backgrounds. In England, he produced such lavish spectacles as "Jane Shore," "Robin Hood" and "King Henry VIII." On his return to New York he produced "The Ghost," "The Corsican" and "The Stain", the latter an American political drama.
