I watch Legion it's been very interesting so far. I will record Legion. I have no idea how to get a video of the behind the scenes stuff without just recording it on my phone, and uploading it to my YouTube account....Which I would gladly do if needed.
However, I wouldn't be surprised if its just the pre-recorded clips of Ridley Scott talking about the movie followed by a shortened version of the trailer we already saw. I see these companies do this a lot to be honest. They advertise a sneak peak and then just show the trailer that's already out.....still im glad they are marketing this finally.
