Florence Lois Weber was an American silent film director, screenwriter, producer and actress. She is identified in some historical references as among "the most important and prolific film directors in the era of silent films". Film historian Anthony Slide has also asserted, "Along with D. W. Griffith, Weber was the American cinema's first genuine auteur, a filmmaker involved in all aspects of production and one who utilized the motion picture to put across her own ideas and philosophies".

In film and video production, split screen is the visible division of the screen, traditionally in half, but also in several simultaneous images, rupturing the illusion that the screen's frame is a seamless view of reality, similar to that of the human eye. There may or may not be an explicit borderline. Until the arrival of digital technology, a split screen in films was accomplished by using an optical printer to combine two or more actions filmed separately by copying them onto the same negative, called the composite.
