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 (Arnold Schwarzenegger) and venomous Poison Ivy (Uma Thurman). Batman has more than Gotham City to protect: the youthful eagerness of crimefighting comrades Robin (Chris O'Donnell) and Batgirl (Alicia Silverstone) 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!
