Most X-Fans will likely know most of the trivia and comic references that packed Days of Future Past, but this six-minute video still probably has a few you missed. For instance, the deleted Rogue scene it describes sounds pretty great — I'm kind of sad it wasn't included. I bet Anna Paquin is, too.
Although since Anna Paquin's Rogue was depowered by the end of X3, how could she have replicated Kitty Pryde's powers in DoFP? Did she get them back, like Magneto got his powers back? Was the mutant "cure" a bust? I assume it must have been, because otherwise the Sentinels probably would have been forcibly curing mutants all these years instead of straight-up murdering them.
Feels like someone should have mentioned all this at some point. Enh, maybe it's in another deleted scene or something. Whatever. Watch the video.
