Briefly: Tomorrowland has been one of the biggest stories surrounding Disney’s D23 Expo this weekend, as you can tell from our coverage of the sci-fi film so far. Today at the convention, Disney showcased the mystery box from earlier this year and talked about the contents. They even showed some animated footage that was supposedly from the box. None of this means anything concrete right now, but you can read the breakdown of the event over at /Film.
