Re: Give Robin Williams a role
I don't picture him as Riddler, but he could easily play a smaller, much more low-key character. Maybe something like Rupert Thorne or even Penguin, functioning in the story similar to how Falcone and Maroni did in the previous two films.
You do not fear death.
You think this makes you strong. It makes you weak.
How can you move faster than possible,
fight longer than possible,
without the most powerful impulse of the spirit:
The fear of death.
