Let's All Go to the Lobby (officially known as Technicolor Refreshment Trailer No. 1) is a 1957 animated musical advertisement played in theaters before the beginning of the main film or before intermission, featuring animated food items urging the audience to buy snacks sold in the theater lobby. It was produced for Filmack Studios and directed by Dave Fleischer. Filmack has continued selling copies in the decades since its production. The company estimates that 80% of independent theaters have screened the film at various points, and it is likely the most viewed snipe. In 2000, Let's All Go to the Lobby was selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant". Content The film consists of six shots. The most recognizable of these depicts four animated food items (from left to right: candy bar, popcorn, candy, and a soft drink) singing and walking leftwards. In the foreground before these characters are silhouettes of audience members, creating an illusion of depth, a standard technique of the medium. In a later shot, a group of four consumers are depicted enjoying their purchased food items. The eponymous song of the film is set to the same tune as "We Won't Be Home Until Morning", "The Bear Went Over the Mountain", "For He's a Jolly Good Fellow", and "Marlbrough s'en va-t-en guerre" (). While the origins of the melody are lost, it was already well-enough known in the early 19th century to be used for a passage in Wellington's Victory (1813) by Ludwig van Beethoven. Daniel Eagan argues that "[w]ith its simple, repetitive lyrics and streamlined animation, Let's All Go to the Lobby has a hypnotic pull that is as compelling today as it was fifty years ago." He also notes that by choosing not to simply photograph the offered items, the creators of the film avoided using brand names for the products for sale. Background and history The Chicago-based Filmack Studios, originally known as Filmack Trailer Company, was founded in 1919 by Irving Mack. The company specialized in the production of newsreels and promotional material for theaters. The film is technically known as a snipe, which is defined as material displayed on a projection screen without being part of the featured presentation. This includes advertising material, previews of coming attractions, courtesy requests for the audience, and notices concerning the concession
