As a character in the movie The Thin Man, Asta was the playful pet dog of Nick and Nora Charles, tugging them around town on his walks, hiding from danger, and sniffing out corpses. ("Asta, you re not a terrier, you re a police dog," Nick tells him.) The character later appeared in the sequels After the Thin Man, Another Thin Man, Shadow of the Thin Man, The Thin Man Goes Home, Song of the Thin Man, as well as the 1950s television show The Thin Man.
