Mysterious Mose is a 1930 Fleischer Studios animated short released through Paramount Pictures as part of the Talkartoons series.
"Mysterious Mose" was a song from early 1930, written by Walter Doyle and first recorded by Ted Weems and his Orchestra.
The film escalates into chaos, which ends when Mose bursts, revealing him having been an automaton (full of cogs and springs) the whole time.
The film utilizes puppetry, stop motion, and silhouette animation to tell the story of an otherworldly creature preparing a celebration in a cemetery.
Walsh and Caballero used the song "Mysterious Mose", recorded in 1930 by Harry Reser and his Radio All-star Novelty Orchestra.
