You know speaking of that sequence, I've felt for some time now that Adam West would have been perfect as the old guy who stands up to the Joker and is then told he reminds the Joker of his Father.
I know by the way that the guy who played him also appeared in Batman and Robin.
You mean Senator Patrick Leahy (D-VT)? He's a big Batman fan. He also played the governor of the Utah Territory in "Showdown," the Jonah Hex episode of Batman: The Animated Series
. (And he played himself in B&R.)
