Howard the Duck is a comic book character in the Marvel Comics universe created by writer Steve Gerber and artist Val Mayerik. The character first appeared in Adventure into Fear #19 (Dec. 1973) and several subsequent series have chronicled the misadventures of the ill-tempered, anthropomorphic, "funny animal" trapped on human-dominated Earth. Howard's adventures are generally social satires, while a few are parodies of genre fiction with a metafictional awareness of the medium. The book is existentialist, and its main joke, according to Gerber, is that there is no joke: "that life's most serious moments and most incredibly dumb moments are often distinguishable only by a momentary point of view." This is diametrically opposed to screenwriter Gloria Katz, who in adapting the comic to the screen declared, "It's a film about a duck from outer space... It's not supposed to be an existential experience".
