This short shows the entrances of the various Hollywood studios, then specifically visits Warner Bros. / First National Studios. We start at the casting office, then see Busby Berkeley and choreographer Bobby Connolly working with chorus girls on production numbers. Then come some candid shots of several contract stars. Finally we see comedian Hugh Herbert filming a scene for an upcoming release, then the various behind the scenes steps that transition the raw film in the camera into the finished product.
