"Can you imagine me opening up my ears and hearing their voices every day of the shoot?" the 73-year-old continued. "I was just weepy with joy. They’re both prolific, as you know, and have a huge body of work."

As it turns out, Goldblum learned during filming that Ariana, 32, had been a fan of his for years—and she had a photo to prove it.

"Halfway through the shooting, Ariana says, 'Look, we took a picture together,'" he recalled. "I was like, 'What were you doing at that show, The ­Pillowman, on Broadway?' And she tells me, 'I came to see it with my mom. I was 12. We came two nights in a row and waited for you backstage so I could take a picture with you.'"

"She showed me this picture of us," he noted, "and I said, 'Send me that immediately!'”

Indeed, Jeff's time on the Wicked set was nothing short of magical.

"I’m the luckiest boy in the world," he told W. "Can you imagine? The music that comes out of Cynthia and ­Ariana—the artistry and the mastery and the humanity and the depths of their beauty—is just a gift to the world."

For the Jurassic Park alum, this chapter of his career has exceeded his expectations.

"This year—and the last decade—has been gratifying and delicious and dreamy," he shared. "I pinch myself every day. My gratitude is bursting—busted out all over."
