Chills and thrills: will Gotham City be put on ice? George Clooney is Batman as the dark knight battles his greatest threat yet: cold-hearted Mr. Freeze (Schwarzenegger) and venomous Poison Ivy (Thurman). Batman has more than Gotham City to protect: the youthful eagerness of crimefighting comrades Robin (O'Donnell) and Batgirl (Silversone) puts them frequently in harm's way. New very special effects include a wild sky-surfing sequence and Freeze's outrageous ice-blasting arsenal. It's state-of-the-art excitement from our Batfamily to yours.
