40. Kate Hudson
Worst Performances: Fool's Gold (2008), Bride Wars (2009), My Best Friend's Girl (2008)
To think, Kate Hudson once gave an excellent, Academy Award-nominated performance in Almost Famous (2000), one of the new millennium's best movies. It's mind-boggling how an actress with such a magnificent introduction into Hollywood could have gone on to lose all of her appeal by committing herself to brutally unfunny scripts (Bride Wars, My Best Friend's Girl) and then have to resort to guest-starring on Fox's Glee to regain some of that old mojo. She's a true legend of the fall-off.
