i love the Superman Fleischer cartoons of the 40s -- they have an exquisite art design and are, for the most part, wonderfully animated. the Fleischers never had budgets so good as with these series of shorts for Paramount.
while re-watching "The Mechanical Monsters" episode, one of the early classics, i thought i saw a big animation jump. i thought for sure it must have been a film print scratch or artifact. upon further review, at least this print (the one from the Bosko DVD collection as well as one up on youtube) has two characters pop up and disappear in a frame or two.
its much more obvious in motion, check it out at around 3:03/3:04:
on the stop motion side of things, Robin Yannoukos' latest film "Alice's Attic" from the UCLA Animation Workshop and Bix Pix Entertainment is up for the Student Academy Awards and is also featured on VSM Cinema here. the sharpness and animation smoothness is amazing, especially for "student" work. its got a great Brothers Quay type aesthetic to it, without getting too abstract that it alienates its audience, with a little Barry Purves thrown in for good measure. it must've been a lot of fun collecting all those little props! at any rate, highly recommended.
