The actress, who received a Golden Globe nomination for her breakthrough performance in 1994's Interview with the Vampire, said she finds the positive reaction from the public rewarding.
She told Moviefone: "I'm proud of so many movies. I've always done things that... I was proud of Virgin Suicides.
"I'm proud of a lot of things in my career. Eternal Sunshine of the Spotless Mind, I was very proud to be in that movie.
"When you reach an audience of people enjoying films that you do, it's so satisfying as an actor."
When questioned further, she said: "Because you want to be part of storytelling - and to affect people is what your job is. And that is the best when it works and people really celebrate the movie and they come up to you and are emotionally moved by it.
"I mean, that's your job. So, when that happens and all of it falls into place - and it's a good film - it's great to be a part of that."
