Chris Pine is having a quarter-life crisis

The actor — who turned 30 in August — admits he’s been thinking about his own mortality and is working out what to do with his life.

“I feel prematurely old,” he says. “I’m actually having this major belated quarter-life crisis. I turned 30 in August. I’ve been thinking a lot about mortality. A lot about what I’m going to do with my life and how to enjoy it.

“One of the things I’m going to work on is being more spontaneous, letting go, embracing the beauty of come-what-may.

“I’m more cerebral than I want to be.

“Sometimes I think I need to get crazy. Go to Vegas. Do some drugs. Get some hookers. Gamble it all away. And it never happens. I usually just end up at home on my couch — reading.”

Pine recently admitted he was “intimidated” working with Denzel Washington on their new movie Unstoppable.

“Man, I was nervous about that,” he said. “Knowing I was going to go head to head with Denzel on the entire film, it was incredibly intimidating, but like they say, ‘If it scares you, you’ve got to face it.”

Unstoppable follows two railway workers who try to stop a runaway train carrying dangerous chemicals.

Chris was willing to tackle his own stunts but opted against anything which could have resulted in serious injury.

“I tried to do as many as I could but it’s a hairy thing with those trains, because it’s not like doing a fight scene with another person where you can say, ‘Stop’. You’re dealing with three tons of fast-moving trains,” he said.

“I hear that Tom Cruise does every single one of his stunts, but I decided if it’s going to endanger my life, I’m giving it up to the guys who know what they’re doing.”
