1. Mary Magdalene Horowitz - All About Steve (2009)
Oh boy: this is the big one. All About Steve is easily the worst Bullock film to date. The same year she pulled off The Blind Side, she also pulled out this crapshow. With such an all-star cast, though, it's hard to think about how this could have gone so wrong. Bradley Cooper (who recently proved his acting chops in Silver Linings Playbook), Thomas Haden-Church (who rarely disappoints), and the ever-hilarious Ken Jeong, all appear in this incredibly disappointing pseudo-road trip movie. You know what? I'm going to copy and paste literally the description from IMDB and you tell me if this sounds like a good idea for a movie: "Convinced that a CCN cameraman is her true love, an eccentric crossword puzzler trails him as he travels all over the country, hoping to convince him that they belong together." Does that sound like something you'd want to see? The answer is no. And why Bullock, who has attached herself to some very successful movies in the past, would sign up for such a thing is a mystery to me. This film earned Bullock a Razzie, and man was it ever deserved: her Razzie acceptance speech is funnier than the entirety of this movie. Do yourself a favour and never see it.
