Star Wars: The Old Republic. Saw the trailer when it was first aired, and my jaw dropped. A beautiful trailer in every way. I love Bioware :oops:

Oh, and if it counts, the Assassin's Creed II: Lineage shorts. Didn't expect much from a live-action version, but with the original voice actors playing their roles it worked out very well.
