Answer by David Dobkin:
Absolutely fantastic. He’s the most exciting actor I’ve ever worked with. His ideas are limitless, his enthusiasm is infectious, he loves making movies, and he makes you love the process with him.
It was an honor to work with him on The Judge because it was his most in-depth and dramatic role. He really put himself into the movie. You get to experience more of who Robert Downey Jr. is as a human being in The Judge than any other he has ever made.
