Kirsten Dunst grew up before movie fans' eyes in films such as "Interview with the Vampire: The Vampire Chronicles" and "The Virgin Suicides," and she became a big star in the "Spider-Man movies.

She is now back at work in "All Good things," starring opposite Ryan Gosling and playing a woman who goes missing shortly after her marriage to a wealthy real estate heir unravels.

The film, which opens in the United States on Friday, is inspired by the notorious 1982 missing person's case in New York city centering around the wealthy Durst family.

Dunst spoke to Reuters about the film, her co-star Gosling, and the new "Spider-Man" reboot.

Q: Kathie Durst's body was never found and no one was charged with a crime. Do you think Robert Durst murdered her?

A: "I think he did because why would the Durst family not help find their daughter-in-law? With all the money and power they had, they could have had every cop searching for her. They did nothing."

Q: Any memorable days on the set?

A: "I'd say the scene where Ryan takes me by the hair and pulls me out of the house. The next day Ryan sent me flowers because he felt bad for having to pull my hair. I was trying to make him feel okay about having to do it, but he still had a difficult time."

Q: It is the first movie you shot after being treated for depression in 2008. Was there a reason to choose this film?

A: "I agreed to do this movie two or three years before we shot it. But whatever energy was moving through me at the time made this the perfect film to do. It felt freeing."

Q: How so?

A: "Because of the people I met during this period, I changed the way I approach acting and film -- the way I work personally before I even start filming. Before I would do the rehearsal process with everyone and I wouldn't plan my whole other world. I took a new interest in the process."

Q: You started working professionally at age 3. You're 28 now. How is acting different today as an adult?

A: "When you're younger, your reality is different. Everything is fun. You're doing it more for other people. Now it's for me, so that's what changes."

Q: Is acting easier when you're young because kids are generally considered to be more open and receptive?

A: "Maybe it's easier. Your intuition is more vulnerable then. When you get older, people expect you to be vulnerable but also tough. That makes no sense -- that as an actor you're supposed to be emotional (on-screen) but then have a thick skin about things (off-screen). I think actors are more sensitive -- you take in a lot more. So you've got to balance out what you decide to take in and what you don't."

Q: How do you feel about the new reboot starring Andrew Garfield as Spider-Man and Emma Stone as Gwen Stacy?

A: "I really like Emma Stone and Andrew Garfield a lot. I think they'll be great. It's just sad that there wasn't a proper ending (for the trilogy). We didn't know when we shot the third one that it would be the last. I wish we would have known. Maybe we would have cherished that time a bit more, knowing it would be the last one for all of us."

Q: Did you think there would be a fourth?

A: "They were starting to put together a fourth but then it was like, 'Oh, okay, I guess we're not doing it.' But in the long run, it's great we have these three movies. It was a very special time for all of us."

Q: You directed two short films. Will you continue?

A: "I will direct a film one day. I just need to find a project I really want to do. Right now the focus is on acting. I've worked for so long that I can afford to take breaks and wait for something special. Everything is at the perfect pace it should be at."
