This is pretty weird: A 1921 animated silent movie. From the description at IFILM:

This is one of the films of prolific American animator and cartoonist Winsor McCay, whose work influenced some of the classic cinema titles like Salvador Dalí and Luis Buñuel’s L’Age d’Or, Mary Poppins (1964), Dumbo (1941), King Kong (1933). Joshua Glenn of the Boston Globe has created an audio slideshow presentation that traces these influences.
