This isn't behind-the-scenes stuff, though. In response to Peter Dinklage's criticisms, Disney put out the following statement:
To avoid reinforcing stereotypes from the original animated film, we are taking a different approach with these seven characters and have been consulting with members of the dwarfism community. We look forward to sharing more as the film heads into production after a lengthy development period.
Now, leaving aside whether Disney was correct to commit itself to such an approach in the first place, it's clear they've now gone back to precisely the sort of portrayal that Dinklage was criticising. This is
public flip-flopping, and it looks craven to me.
