he/him
I have a horrible feeling this is going to be stuck in development hell for ages. This quote, albeit brief, doesn’t fill me with confidence. He said himself “it’s a long road ahead”, and I think the subtext there is that it’s not going to be easy or straightforward.
He said in another interview they haven't even really begun anything, including figuring out the direction the film will take tonally, so that's probably the main reason for his answer
