The fourth Batman movie in the franchise. Batman (a rather strangely-cast Clooney) is still with Robin (O'Donnell) from the last movie, this time having to save Gotham from a doctor-turned-villain Mr. Freeze (Schwarzenegger against type). And if you thought Arnie was huge, take a look at Jeep Sweson (as 'Bane'), who unfortunately died shortly after the movie was released in 1997.
My personal favourite in the series, but a box-office flop which made its money back via video & DVD sales in the late 90s/early 2000s.
