Supposedly Grumpy, Happy, Sneezy, Sleepy, Dopey, Bashful and Doc will play a “pivotal role” in Disenchanted that includes them participating in a musical number. This information comes from The DisInsider, which also provided supposed details about Disenchanted. Although the sequel is coming out more than a decade after its predecessor, evidently that same amount of time won’t have passed within this fictional world, with Disenchanted either taking place shortly after Enchanted or, at most, just a few years later.
