Bugs Bunny makes a cameo in this Private Snafu short, another famous character voiced by The Man of Thousand Voices, Mel Blanc.
Actor Billy Bletcher voices the ominous gas cloud. Although the cartoon has humor, it was intended to train U.S. troops as well.
The stellar talent behind this wartime short included director Chuck Jones, writer Theodor Geisel (aka Dr. Seuss), and the character's creator, Frank Capra.
SNAFU is an acronym for 'Situation Normal, All Fouled Up' - at least that's the dictionary version. In reality, the 'F' is translated to 'F***ed'.
