1. Sandra Bullock in 'Speed 2'
The original 'Speed' is a '90s classic with a stupidly brilliant premise: there's a bomb on a Los Angeles city bus and it will go off if the vehicle goes below 50 mph. The sequel, which moves the action to a cruise ship, is just plain stupid. Keanu Reeves was smart enough to jump ship, leaving his co-star Sandra Bullock (along with his replacement Jason Patric) to deal with the criticism.
What she said: "It doesn't make sense: a slow ship, slowly going towards an island. This is one of the movies I wish I hadn't made."
2. Robert Pattinson in 'Twilight'
R-Patz made his name playing a bubbly emo vampire in the popular adaptation of Stephenie Meyers' novels and has spent the last decade trying to forget the role. The guy badmouths the movies so often that he has a Tumblr account dedicated to criticizing him about the franchise.
What did he say: "There's a lot of things in the 'Twilight' world that doesn't make sense. Like, why do they still go to high school? They're a hundred years old."
3. Christopher Plummer in 'The Sound of Music
Who doesn't love that heartwarming musical classic about the Von Trapp family? Apparently, to Father Von Trapp himself. Over the years, the late acting legend repeatedly complained about how the role came to define his career. He even referred to it as "the sound of mucus" (the original title was 'The sound of music') in the 'New York Times'.
What did he say: "It was so horrible and sentimental and cloying. You had to try really hard to try to infuse it with a little humor."
4. Viola Davis in 'The Help'
Although it earned her a best actress nomination, Viola Davis has mixed opinions about her role as the maid Aibileen Clark in the period drama "The Help." She has stressed that her problem with the film was never the crew or her experience on the set. But she has expressed her regret at the film's portrayal of her character's story.
What she said: "I just felt like the voices of the maids weren't heard at the end... I know if you make a movie where the whole premise is 'I want to know what it's like to work for white people and raise kids in 1963 ', I want to know how you really feel about it. I never felt it in the movie."
5. George Clooney in 'Batman & Robin'
Before Christopher Nolan could resurrect the Batman franchise, someone had to kill off the old version, and that person was George Clooney. The film had him fighting Arnold Schwarzenegger's Mr. Freeze, and the film left the lead man feeling cold, and we're not just referring to his nippled bat suit.
What He Said: "It was a movie where it was hard to get right. In retrospect, it's easy to look back and say, 'Wow, that sucked and I was really bad.'"
6. Channing Tatum in 'G.I Joe'
Following the massive success of 'Transformers,' Hasbro launched into creating new movie franchises out of its beloved toys. In 2009 came 'G.I. Joe: The Rise of Cobra', with Channing Tatum in the lead role based on the military figure. But the star didn't sign up for the role, he was recruited: he had signed a three-picture deal with Paramount and the studio basically forced him to do it.
What did he say: "Look, I'll be honest, I hate that f- movie. I hate that movie. They pushed me to make that movie."
