My understanding is he’s simply producing it and not necessarily close in the creative aspect of it. My hope is they keep it all true to how the message & characters are presented in the original ride rather than not.
Another hope is that ‘maybe’ they might have the ride restored back to it’s former glory ‘before’ the movie is released, just to prove a point to upper management about park original IP being successful in it’s own right and how ‘that’ is a valid medium for true creativity without film IP having to be tied into it.
