After quite a wait, Dreamworks Animation has finally relented to allowing its movies on iTunes, which means the company's catalog is more or less up for grabs. Kung Fu Panda is one title customers have been waiting for, and Monsters vs. Aliens, Bee Movie, and Madagascar 2 are available as well. Shrek the Third is the only movie of that series available at the moment, unfortunately, and there's no sign of Megamind or How to Train Your Dragon, so the catalog isn't complete by any means.
Still, progress is progress, and this deal means you and your kids have a few more options when you jump into iTunes to find a movie to watch. Whatever issues there were between Dreamworks and Apple have apparently been worked out, to some degree at least.
