This first one is the long one from 2011 San Diego Comic Con. It’s a little spoiler-ish because it’s so long, but it’s a really engrossing, immersive watch that you can’t turn your attention from. The second ont is the less spoiler-ish less than two minutes one, which is just as compelling.
Enjoy.
On, and they’ve finally relased the start date: October 16th.
