I think Ben's said in the past he's a Superman fan.
I am, too --- mainly of the 1940s Fleischer shorts, the radio series, the 1990s Superman animated series, and the first two films in the series starring Christopher Reeve.
The film I'm linking to off of YouTube is perhaps the best-animated version of Superman since the Fleischer era. Full-animation just isn't done with characters like this anymore because cheaper, limited animation from overseas has proven to be profitable and acceptable to most audiences. The lushness of full-Fleischer, let alone Disney, hand-drawn animation is a thing of the past. It was done in more by corporate greed, mismanagement, and bad stories rather than the talent of animation crews and trendy CG.
"Superman Classic" was directed and animated by Robb Pratt, a Disney animator, along with some friends. Lois and Clark are voice-acted by the married couple of Jennifer and John Newton. John Newton was the original Superboy for the first season of the late 1980s series "Superboy".
Note: A smaller version of this video file exists on Robb Pratt's website. It's an easy download and can probably be used on portable video players without any reconverting.
The YouTube video version is higher-res...
P.S. -- This short is relatively fresh. It was released to the web on February 6th. For obvious legal reasons, it's a free release.
