Chills and thrills: will Gotham City be put on ice? George Clooney is Batman as the dark night 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 crime fighting 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. Its state of the art effects are not to be missed.
