“He is an experience,” Lively, who appeared giggly and slightly nervous, told David Letterman Thursday. “And when we were making the movie, we were trying to think of something to get the crew because they needed something nice after working with him for that long.”

The gift? Shirts that said “I Survived Oliver Stone,” she joked.

When asked by Letterman how Stone reacted to that, she replied, “He didn’t care for that.”

The “Gossip Girl” actress likened working with Stone to riding through “Jurassic Park”: both beautiful and terrifying at the same time.

She continued, “It’s inspiring and you feel so honored to witness it. And then there’s a moment of fear. And then you see something that’s cute and cuddly and it spits venom at you. And then it gets more intense. And then the T. rex is biting your head off. And then you go down a drop and you feel like you’re going to die. But then it’s like refreshing at the end.”

Lively offered more mild words about Stone on “Good Morning America” earlier this week: “It’s such a honor [to work with him]. He’s an intimidating man just because of his previous work. And then you meet him and he’s so intense and passionate. And he expects so much out of you.”

Stone certainly has a reputation in Hollywood, one that the director is well aware of.

He told the Hollywood Reporter in a recent profile, “I was crazy for many years. ... So is everybody, you know. But now, I’m pretty sane. There’s been so much craziness in my life — and there still is — but it gets out through the work.”

Stone, meanwhile, had kind words for Lively — and her looks — on CBS's “This Morning.”

“She’s extraordinary,” Stone said Friday. “She’s got kind of a Grace Kelly ... cool elegance. Blond and beautiful. Good to the eye. I always try to cast pretty people, good looking.”

Stone previously called Lively “smart as a whip” to the Huffington Post and predicted she would became a bona fide movie star.
