It'd be extremely interesting if out of every development-hell Disney parks film we've heard of, Figment breaks thru the glass barrier and gets an official greenlight.
My main concern on it getting news at D23 is that film 'insiders' leak everything and anything, and that especially includes things like "Disney is approaching so and so to direct this film", and we've seen nothing on anyone being approached to direct this movie. Is it likely this type of scoop has escape the grasp of the clout-hungry movie 'scoopers' due to Figment's low popularity beyond the gates of WDW? Probably, and I'd believe that too.
My main wonder if it's still penned for Disney+ or if they want to pen it in for a theatrical release...
