Leading up to his world arena tour, Hugh Jackman stopped by The Tonight Show With Jimmy Fallon April 8. The star admits that he never thought he’d have the career he’s had—playing Broadway and Wolverine—let alone be able to sell a world tour.

“Almost everything in the last 25 years has surprised me. Even the musical theatre thing,” he told host Jimmy Fallon. “When I came out of theatre school—there was a musical theatre school where I studied, was not in that, I was in the theatre school—I had never sung before when I went for my first audition for Beauty and the Beast. From that moment on everything has been a bit of a surprise.”

Jackman has been training for the massively scaled tour for years. “I've been working on this show probably for eight years,” he said. “But for the last two years, knowing I was going to do this, I've been in training, tap-dancing, singing, doing the whole thing, and I'm just going to lay it all out there.

“I have an orchestra. I have ten singers and dancers. There's 193 people involved in this one-man show.”

Since the last time he visited The Tonight Show, Jackman became a Grammy winner for The Greatest Showman album and shared his love for the film.

“Keala Settle, who played the Bearded Lady—that was her first movie. The director Michael Gracey, that was his first movie, Justin [Paul] and Benj [Pasek] who did Dear Evan Hansen and La La Land it was their first movie,” he said. “There were so many people who started on this job, and I kind of feel bad for them because it's all downhill from here. But to me it's a testament to belief.”
