AceShowbiz - Kristen Stewart might have starred in dozens of movies, but she only likes a few of them. In a revealing new interview, the Bella Swan depicter in the "Twilight" film series admitted that she only "made five really good films, out of 45 or 50 films."

The 31-year-old made the honest confession when sitting down with The Sunday Times. "It's a total crapshoot," she said. "I've probably made five really good films, out of 45 or 50 films? Ones that I go, 'Wow, that person made a top-to-bottom beautiful piece of work!' "

When asked about her favorite projects, Stewart mentioned that the two of them are the works of Olivier Assayas, who directed her in "Clouds of Sils Maria" and "Personal Shopper". She gushed, "I love Assayas’s movies."

"I'd have to look at my credit list. But they are few and far between. That doesn't mean I regret the experience [of making them]. I've only regretted saying yes to a couple of films and not because of the result, but because it wasn't fun," the ex of Robert Pattinson further explained. "The worst is when you're in the middle of something and know that not only is it probably going to be a bad movie, but we're all bracing until the end."

The "Spencer" star, however, refused to point out which projects that she considered "bad." She said, "I'm not a mean person - I'm not going to call people out in public... But it's like starting to date someone and going, 'Woah! I don't know what we're doing!' But when you're in the middle of a movie you can't just break up."

Earlier this month, Stewart confessed that the one regret she had about portraying Princess Diana in "Spencer" is she's "not a mum yet." She continued, "I need that to feel authentic. It's the one part of playing her that I felt disloyal about."
