Some Hollywood stars get excited easily, especially when they think they've stumbled upon the cause of all causes. Add in the hipness factor currently attached to being green and you're bound to get some A and B listers shoving their pedicured feet in their mouths while trying to assert their eco-cred. Some of the Hollywood stars we've highlighted here meant well, but others were more calculating (or simply clueless) in their green posturing. Regardless of motive, it's important to call them out when it happens, even if it's to just have a good chuckle at their expense. Celebrities — and I know I'm grossly generalizing here — are surrounded by people who tell them yes. But they can't just walk onto the environmental scene with a hybrid and a hit movie and expect to be welcomed as a player. The best green stars do before they say; these stars just say — and badly.
