Before the show begins at a movie theater, a patron stands and walks to the lone empty seat. A second patron switches to the seat just vacated. A third and a fourth and soon everyone in the house is caught up in a flurry of seat-switching. The newsreel contains a few gags and caricatures, then there is a sing-along of the title song. The feature spoofs The Petrified Forest. Finally, an annoying gosling sneaks into the projection room and plays with the controls before getting caught in the gears.
Bacall to Arms, released in 1946, contains the same basic plot as this cartoon, and even reuses some animation.
The cartoon features a parody of MGM'S lion logo with a rooster crowing instead of the usual roaring. Interestingly, MGM would end up owning this short due to their purchase of United Artists (which had owned the pre-August 1948 WB cartoon library, which this short was a part of) in 1981.
The dubbed version, which is uncut, is shown on Boomerang.
