Dreams of a Rarebit Fiend: The Pet (Dir. Winsor McCay, 1921)

Winsor McCay, renowned for such comic strips as 'Little Nemo in Slumberland,' earlier explored dream imagery with his 1904 strip 'Dream of a Rarebit Fiend,' in which a character claims his horrible nightmares are caused by eating Welsh rarebit (a highly seasoned dish made with melted cheese and beer). In 1911, McCay began doing film animation, personally drawing every frame on rice paper; his most famous effort is 'Gertie the Dinosaur' (1914). He made four films based upon his Rarebit Fiend series; note the amazingly complex pan across the city following the monster, when the sky is filled with planes and a zeppelin, each freshly-draw for every frame!
