Making of Assassins Creed 2

Here is a great look at story-telling as set up for a new version of a video game.  From a technical perspective, a great 'behind the scenes' with green screen for all live action forcing all 750 shots to have backgrounds created in post.  One of the most frustrating things is often the perception that green screen is the 'easy answer' to creating an environment and avoiding travel for a field shoot or challenging location.  It is an option yes...but often it requires much more work. The specifics don't get very detailed on this aspect until about halfway through but notice the legions (legions...get it....never mind) of computer programmers and artists that are creating the backgrounds and tweaking the tracking to make it realistic.
