RENEE MONTAGNE, HOST:

Good morning. I'm Renee Montagne. "Batman V. Superman" opens today, also the senator from Vermont versus Superman. Patrick Leahy has a cameo in the movie as a senator in a congressional hearing on whether Superman is a tyrant or a hero. It's not the first time the Batman fan, Leahy, traded D.C., for DC Comics. Once, he stood up to the Joker.

PATRICK LEAHY: (As Gentleman at Party) We're not intimidated by thugs.
