Kristen Stewartknows not every movie she has appeared in has been a hit.

In an interview withThe Sunday Times,the 31-year-old actress, who playsPrincess Dianain the upcoming biopicSpencer, confessed to only liking a handful of the dozens of films she has worked on throughout her career.

“It’s a total crapshoot,” said Stewart. “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!'”

“I’d have to look at my credit list. But they are few and far between,” the star continued, noting, “That doesn’t mean I regret the experience [of making them].”

Stewart said she has “only regretted saying yes to a couple of films.” Though it wasn’t over the result, but rather that “it wasn’t fun.”

“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,” she explained to theTimes.

Earlier this month, Stewart toldThe Daily Mailthat sheonly had one regretabout her performance inSpencer, which hits theaters on Nov. 5. “I’m not a mum yet,” she said. “It’s the one part of playing her that I felt disloyal about.”

In another recent interview withEntertainment Weekly, Stewart said she’sbeing more selectiveabout which films she chooses to work on.

“I used to be really intentionally the opposite of precious in terms of choosing projects. For a minute there I was like, ‘I’ll do f—— anything!'” Stewart confessed. “And honestly, it was a good place to be for a minute.”

She added, “But I think now I’m going to be a little more careful. I think I have a better nose for what’s going to be fruitful for me personally, as an experience, if not necessarily what’s going to thrive out in the world.”
