Warner Bros. has just posted most of the Fleischer cartoons to their You Tube channel. If you have never seen these classic Superman cartoons I highly suggest you take a few minutes out of your day and use the links provided to enjoy some classic Superman toonage. Here is the first episode embedded for you, with links to the rest underneath.
The Fleischer & Famous Superman cartoons are a series of seventeen animated Technicolor short films released by Paramount Pictures and based upon Superman.
The pilot and first eight shorts were produced by Fleischer Studios from 1941 to 1942, while the final eight were produced by Famous Studios, a successor company to Fleischer Studios, from 1942 to 1943. Superman was the final animated series initiated under Fleischer Studios, before Famous Studios officially took over production in May 1942.
Although all entries are in the public domain, ancillary rights such as merchandising contract rights, as well as the original 35mm master elements, are owned today by Warner Bros. Animation. Warner has owned Superman publisher DC Comics since 1969.
