If you have HBO's HD VOD via your cable provider (i.e. Comcast or Verizon FiOS) congratulations, as you should also have access to a few 3D movies. Multichannel News reports Coraline, Ice Age: Dawn of the Dinosaurs, Monsters vs. Aliens and Clash of the Titans are all available for your viewing pleasure. Of course, since it's HBO we're expecting some cropping/compression malfeasance but why don't you give it a look and tell us how they're doing.
