Winsor McKay (USA, 1866), the creator in 1905
of the comic strip "Little Nemo in Slumberland", made
ten animated movies between 1911 and 1921, almost all of them conceived
as overtures to his vaudeville act. The first one,
Little Nemo (1911), consisted of thousands of drawings,
How a Mosquito Operates (1912) and
Gertie the Dinosaur (1914).
His most ambitious film, The Sinking of the Lusitania (1918), required 25,000 drawings.
