Rees is known for directing The Brave Little Toaster, creating the special effects for Tron, and working on numerous Disney park classics such as Indiana Jones Stunt Spectacular, Alien Encounter, Cranium Command, and Cinemagic in Disney Studios Paris.
So, what could this be? I'll look at some theories below
Captain EO Replacement
We all know Captain EO was supposed to come back as a tribute, but I think most of us would agree it's overstayed its welcome. With Rees's directing experience with things inside the parks, it wouldn't be a stretch to think he'd be working on something to replace the relic of a show. The question is whether or not a new film in the Magic Eye Theater will be followed by a new dark ride next door.
Universe of Energy Refurbishment
Just as Captain EO has worn out its welcome, so has the Ellen version of Universe of Energy. Don't get me wrong, I thoroughly enjoy this version of the original EPCOT Center attraction, but I also have to admit it's horribly stuck in the 90s. Rees could be developing new preshow and ride films to replace the aging Ellen ones.
New World Showcase Film
This is probably the least likely of the bunch, in my opinion, considering it seems Disney is content with simply adding dining and shopping to World Showcase and calling it a day. Still, it'd be great to get a new offering in the area.
