This documentary is currently floating around YouTube and is well worth seeing–particularly if you love early animation. It stars a variety of guests who talk about the work, history and innovations of the Fleischer Brothers…the folks who brought us Ko-ko the Clown, Betty Boop, and Popeye. It’s narrated by Carl Reiner and is very interesting…particularly the portions about their invention of the Rotoscope as well as their three dimensional cartoons.
