Disney animator Robb Pratt decided to create his own traditionally-animated Superman super short and post it on Youtube. It takes elements of Superman throughout the ages, from the old Saturday matinee shorts (in the soundtrack) to a character design that combines all the actors who've played Supes over the years. Interestingly enough, Pratt even used the work of Hugh Ferriss as a basis for the backgrounds. (Hugh Ferriss is an architect / artist whose work is credited for inspiring the look of Gotham City.)
The styling is great, and I of course love the robots. It's also really cool that John Newton, who played Superboy in the 80s, was able to voice The Man of Steel again. My major complaint is that it's not long enough! Of course, no one knows better than me that animation, particularly hand-drawn animation, takes forever. (Thanks for discouraging that career path, film school! Six months to animate sixteen seconds of cartoon, wheeee!) Pratt also has character designs for Wonder Woman on his website, so perhaps he's planning on doing several little vignettes in this "classic" style.
