George Clooney
The 1997 Batman & Robin movie may very well be the worst film of the highly-acclaimed Batman series. Accompanied by Chris O'Donnell, as Robin, Alicia Silverstone, as Bat Girl, George Clooney completed the terrible trio with his failed attempt as Batman. Arnold Schwarzenegger and Uma Thurman's renditions of evil enemies are a close second when terrible performances are awarded against Clooney.
In this Batman film, Batman and Robin are working side-by-side to stop Mr. Freeze and Poison Ivy from taking over the beloved city of Gotham. One could only hope, after watching the film, that there would be no trilogy featuring Clooney in his failed attempt of acting.
