3. Naomi Watts
The lovely Naomi Watts made a whopping four movies over the course of 2013: of those movies, one was okay, and three of them were downright terrible. Forget the rest, though - the one picture she'll be "remembered" for is Diana. Oh, Diana: you horribly executed, Oscar-bating, TV-movie of a movie, you. Watts had good intentions when she agreed to play Princess Diana of Wales in this biopic, of course: shame it's such an embarrassment from start to finish, then. If that sounds hyperbolic, it shouldn't: Diana is one of the worst biopics ever made - hollow, dull and throughly uncinematic, it does absolutely nothing to bring credibility and resonance to what should have been a landmark release. And there's Naomi, right slap bang in the middle of it all. Seriously, if you saw her at a party over Christmas, you'd avoid chatting with her out of embarrassment. That's if she even leaves the house. I think the world will forgive Naomi Watts for Diana, of course, but the fact that she did such an injustice to one of history's favourite people won't exactly have done wonders for her career.
