One of the first and undeniably filthiest animated films of all time was Fritz the Cat, a 1972 adult black comedy that became a pioneer for future animated works for adults. Who says that animated movies are solely for kids? Going back to the 1929 cartoon Eveready Harton in Buried Treasure and through the years of sex-symbol Betty Boop and gross-out Howard the Duck, animation has attempted to appeal to adults in different ways over the years, though without much mainstream success until the '70s and '80s.
