There isn’t going to be 8 minutes of Carrie. They had 8 minutes available and analysed every frame. This doesn’t mean that they were able to use every second of that footage though. I’d say it’s going to be a lot less than that.
Yes I know (plus who’s to say there even is 8 minutes of footage). This is all secondhand information so it’s hard to trust it completely anyway. Just working out the best case scenario. Star Wars is about hope, isn’t it?
