Re: Would Richard Grayson be part of this movie?
With Batman already being a season vet and having done this for..... a while, I would LOVE for him to have brought on Dick as Robin already.
Though, I would prefer they went the Batman: The Animated Series route and say that Dick is currently attending college and it unable to be Robin full time. And maybe we could see a shot of the Robin suit in the Batcave.
As far as going forward after this, I'd love to see them jump straight into Jason Todd and have Dick become Nightwing in his first appearance.
