Cinematography by Christian Matras. Film Editing by L onide Azar. Costume Design by Georges Annenkov. Music by Oscar Straus. It's funny, though, if you think about it.
Film is a non-realistic art form.
It's true enough that a film, unlike a play, can be shot on an actual location instead of a set. But in bringing the action to the audience, it's the opposite. A play shows it to you live, before your very eyes, in real time. A movie shows you a montage of disconnected shots taken at different times, from viewing locations and angles that may be impossible in real life, and shown at different magnifications. Audiences accept and crave what they're used to, with intermittent changes precipitated by trend-setting films.
