Is Kate Hudson that bad? Probably not, but her 'form' of terrible movies (Bride Wars followed My Best Friend's Girl followed Fool's Gold...) and her insistence on so rarely stretching herself (her stock character has gradually been diminished to, simply, a blonde girl) that puts her firmly on this list. And its her phenomenal performance in Almost Famous that solidifies her position. In Cameron Crowes autobiographical rock n roll comedy, Hudson plays band aid (read: groupie) Penny Lane, a confused and vulnerable girl used up by fictional rock group Stillwater. Hudsons conflicted and melancholy in her first big role, thinly covering up her insecurities with jocundity and flirtatious energy. The line Why doesnt he love me? is a trite one, but here, out of Hudsons mouth, its heartbreaking. She's been playing a watered-down variation of this role ever since, with none of the films or her performances in them quite as successful. And still, years of rom-coms havent diminished the brilliance of this portrayal.
