The Cinema Murder.

Aspiring actress Elizabeth Dalston, after rehearsing a murder scene for a movie, is fired by her director at the request of the company's Wall Street backer, Sylvanus Power. Although married, Power plans to make Elizabeth his mistress and offers the unsuspecting girl a dramatic education in England, to be followed by his building a theater for her. Traveling across England after school, Elizabeth witnesses a fight between two brothers, Philip and Douglas Romilly, which ends in Douglas' supposed death. On the steamer to America, Philip, disguised as Douglas, confides in Elizabeth that he was fighting to persuade Douglas not to leave his pregnant lover. Elizabeth believes him and in New York they fall in love. After she convinces Power to produce Philip's play, both the play and her acting are hits. When Power propositions Elizabeth and discovers her passion for Philip, he summons Scotland Yard detectives, but Douglas reappears and clears Philip. Power then graciously admits his defeat.
