The movie musical occupies an interesting position in the film industry. On one hand, like action movies, its dance scenes are all about bodies in motion: dynamism, choreography. Yet, with notable exceptions such as Busby Berkeley, those responsible for putting star hoofers on-screen tended to let them strut their considerable stuff uninterrupted. It’s not to say that the camera always remained static; but you could imagine the likes of Fred Astaire and Ginger Rogers, or the gravity-defying Nicholas Brothers, taking it as a personal affront if they weren’t shown full screen, to fully appreciate their elegance, their athleticism.
