This is an idea I had a while back for an attraction based on the marvel character Dr Strange, in WDS in a potential Marvel land. It would be a haunted house style ride that shares many similarities with Tokyo disneyland's Mystic Manor. However, it would be slightly darker, more realistic and using a lot of the technology seen in Ratatouille.
The story, is that you are secretly working with Dr strange to find and hunt down a villain, (possibly Loki?) and when Dr Strange starts to suspect that loki is hiding in strange hall, you're called in to investigate. When you and doctor strange split up to find Loki, he appears and starts to cause havoc with the mansion, bringing everything to life, tearing away walls and ceilings, blocking your path. Eventually, Dr. Strange will reappear, and he and Loki are caught up in an intense magical battle as you watch on. Eventually, strange wins and as you exit the ride, you see an animatronic Loki being detained by S.H.I.E.L.D agents.
As we saw in ratatouille, it's definitely possible to get movie studios on board to create new scenes for a ride, so why can't they do it in live action? It would be more immersive and a real crowd pleaser to have Benedict Cumberbatch (Strange) and Tom Hiddleston (Loki) appear as their characters in the attraction. It's hard to explain how the effects would work, but if you've ridden Ratatouille, picture gusteau's ghost, but in the forms of Dr. Strange and Loki.
