During the era of the silent film, movies were never really silent. Hidden in plain sight behind the films that made figures like Charlie Chaplin and Buster Keaton into cultural icons, were the musical giants whose compositions defined the very films that captivated a generation of movie-goers. "HOLLYWOOD'S MUSICAL MOODS" is an intimate conversation with some then-living legends from a bygone golden age of Hollywood, a freeze-frame of an era where music exemplified the magic of the movies as much as any leading lad or lady. At a time when new technologies were shaping a rapidly-changing film industry as a whole, musical inventions such as the mighty Wurlitzer organ and the ethereal Theremin made the job of these geniuses a true exploration in creating emotion. Directed with an unobtrusive eye, this hour-long feature lets these masters of mood and music, as well as some of their iconic works, speak for themselves. Sincere interviews are intercut with nostalgic clips and classic scenes to showcase the sheer power with which these scores could command the films for which they were written.

The modern American musical - in film form or on stage - borrows and expands on many genres. A musical and narrative performance full of spectacular showmanship, the musical's place in history is explored in this episode.

In the 1930s and 40s, Eric Porter had established himself as an efficient and innovative all-rounder in the Australian film industry, making a living from sponsored work and cinema commercials. He branched out into producing and directing a dramatic feature film, A SON IS BORN (1946) with Peter Finch and Ron Randell, and whenever he could he explored the possibilities of animation. As an animator, he was largely self-taught but there is evidence that he reached out to Disney for advice and received helpful replies. In 1942, an opportunity arose that changed the course of his career. Through a casual conversation he found himself commissioned to make an animated cinema commercial for local entrepreneurs Bert Appleroth and Albert Lenertz who wanted new and exciting ways to promote their very successful Aeroplane Jelly, a brand of brightly packaged crystals that had attached itself to the current craze for aviation, and was famous for a catchy musical jingle to promote the jelly on radio. For the first time, Porter felt creatively free to develop an animation concept and style, and came up with a two-minute animated commercial called BERTIE THE AEROPLANE. The film was such a success that, like the Aeroplane Jelly song, had a life of its own. It was followed by a second animated commercial, BERTIE THE JET in 1954. In making these two films, Porter was free to experiment with animation techniques and with colour, and the films led the way for his future work in animation, culminating with an animated feature, MARCO POLO VS THE RED DRAGON in 1972, and in television programs. The films also were a vehicle for Porter's own mischievous sense of humour. ANIMATING AEROPLANE JELLY celebrates this turning point in Porter's career - a moment which was also a turning point in the history of Australian animation. The films went further to help to embed the Aeroplane Jelly song as an iconic and much loved part of national popular culture, still loved and sung widely 70 years later, just as Bertie the Aeroplane toys are still marketed widely. The documentary includes an archival interview with Porter himself, and newly recorded interviews with his daughter Gaby Porter, and his animation collaborator, Cam Ford, as well as film historians Ray Edmondson and Andrew Pike. It also includes archival footage of Porter and his studio at work ... and with delightful good humour, at play. The film is a charming labour of love by animation enthusiast and documentary filmmaker, Michael Kraaz.
