Although “The Addams Family” cartoons first appeared in 1930, it wasn’t until 1954 that “The Thing” was alluded to, and not until the late ‘60s that “Thing” appeared on screen as a hand in a box. As a character, Thing is part assistant, part pet, and part family, but is usually used mostly for comedic relief and as a visual gag, until Burton gave Thing a bigger part of the action.
