15. George Clooney – Batman & Robin
Lots of famous names have played the Dark Knight, to varying degrees of success. After all, fans were outraged when it was announced that Heath Ledger would play The Joker, and that turned out pretty well. Anyway, back to Clooney. He only played Batman once, in the critically panned Batman & Robin. Ya know, the movie with the bat nipples. The film stunk so bad that Clooney vowed to never don the cowl and cape again, leaving plans for a second Clooney/Batman flick stuck in purgatory.

14. John Wayne – The Conqueror
We know we mentioned this one in our opening paragraph, but we really need to hammer the point home about how awful it was. Genghis Khan was born in Mongolia, which is part of Asia. John Wayne was born in the middle of Iowa, perhaps the whitest part of the entire United States. After starting his movie career in 1926 and making a name for himself on the big screen, mainly as the star of numerous great Western flicks, Wayne decided to play the role of Khan in the 1956 disaster The Conqueror. Maybe he was just bored after 30 years in the business. Or maybe producer Howard Hughes just drove up to his house with a dump truck full of money. Either way, the movie and the casting choice was terrible and is routinely cited as one of the worst in film history.

13. Kelsey Grammer – The Expendables 3
Sylvester Stallone. Jason Statham. Antonio Banderas. Jet Li. Wesley Snipes. Dolph Lundgren. Randy Couture. Terry Crews. Harrison Ford. Arnold Schwarzenegger. And Kelsey ‘effin Grammer? What?
As a movie series, The Expendables has never taken itself too seriously, which is part of its charm. Bringing together all the biggest action movie stars from the last two or three decades and putting them in one big, over-the-top, muscle-bound, blow-everything-up extravaganza has been fun. But what the hell is the guy from TV’s Frasier doing in the third one? He is literally the last person we would associate with this movie. He plays a retired mercenary-turned-recruiter for tough guys, but it’s barely believable. And that’s saying something, since the whole movie requires us to suspend our disbelief in reality.
