Something I'm surprised Disney hasn't done yet is a Figment/Dreamfinder film. You'd think it'd be a given with all the films based on attractions Disney's been putting out.
It could be great for a few reasons- the original attraction was a celebration of imagination and the creative process, something people of all ages can relate too. It's a character that EPCOT fans have been in love with since the '80s- so parents could see a beloved character from their youth brought to the big screen, and children can be introduced to a fleshed out version of an iconic character.
The characters have gotten a Marvel comics treatment- and they've sold fairly well.
The "theme" for the attraction used to be a wonderful Sherman brothers track- "One Little Spark" that could be adapted to a film fairly easily and bring some classic Disney charm.
A film could introduce the character to fans who've either only ridden the current bastardized version of the attraction, or who've never been to EPCOT. The character would also be fitting for a television series- where every week the duo venture into a new dream. If successful, it could be used as inspiration to fix the current version of the attraction. It could even inspire a new attraction to be built in the Carousel theater in Disneyland's Tomorrowland.
Shows that delve into the "Imagination" if done right tend to connect with audiences on an emotional level that few things can- the '92 iteration of Fantasmic! being a prime example. What was once a celebration of the surrealism and wonder of imagination full of effects that "wow" people of all ages with stagecraft that defies belief has been reduced to a simple water/projection fragmented clip show extravaganza that leaves little to be wondered and little room for an emotional connection.
Of course- I'm still blown away by the horrific treatment Mickey and Minnie are getting for the 90th celebration, an opportunity to bring together Disney fans of every age to celebrate America's most iconic character with an exhibit celebrating Mickey's heritage and evolution in the Disney gallery, a new series of shorts in the various styles of Mickey, and to have Mickey meet and greets in the style of each generation of the Mouse has been reduced to a "Get Your Ears On" promotion relying solely on the current weird version of Mickey and selling Mickey themed foods.
