'Charlie and the Chocolate Factory' preparing for Broadway debut

— -- For the first time ever, the story of Willy Wonka is coming to Broadway.

Roald Dahl's “Charlie and the Chocolate Factory” follows five children who set off on the adventure of a lifetime after snagging golden tickets to tour a chocolate factory.

In New York, the Lunt-Fontanne Broadway theater has been transformed into that magical factory. So far, only a few lucky insiders have seen that transformation first-hand.

A few tantalizing hints we learned about the play:

3 Broadway first-timers will play the role of Charlie.

Flynn told ABC News that he went bananas when he found out he’d landed the role.

"I got a package in the mail and it was a Wonka Bar,” Flynn said. “And I opened it and there was a golden ticket in it that said I had the part. I went absolutely nuts. I don’t even know what happened after that. I went nuts."

Sell added, “It’s just a great story. Roald Dahl’s a genius. I don’t know how he can figure this out. But somehow he does it."

Watch the actors talk about landing their roles in a Broadway play:

Two-time Tony Award winning actor Christian Borle will star as Willy Wonka.

“I think what was scary about Willy Wonka was his unpredictability. And we certainly have that here,” said Borle. “I think we’re excited about unveiling a lot of surprises. But I also want to make him like a recognizable human being. He’s eccentric. But deep down he’s a real person. And actually fundamentally at the end, a generous person.”

Watch Christian Borle talk about one of his favorite moments in the show:

Remember the gluttonous Augustus Gloop?

“For most of the show we carry around these giant fake bratwurst, because we’re from Bulvaria. And they’re huge. I love the prop. It’s literally this long,” Fitzgerald said with arms stretched wide. “It’s the best prop I’ve ever had.”

Watch Haynie and Fitzgerald share some insider secrets about their fabulous props:

Alan H. Green, aka Mr. Salt, just saw the original film for the first time.

“I actually didn’t see it initially. I happened to randomly come across it on Christmas Eve. I was at home eating king crab legs,” joked Green. “And I turned my TV on. And it came on and I thought I should watch it."
