Jeremy Allen White didn't ask Rami Malek, Austin Butler or Timothee Chalamet about playing music icons on the big screen

Jeremy told Variety at the picture's New York Film Festival premiere: "I didn't talk to Austin, I didn't talk to Rami, I didn't talk to Timothee.

"And sometimes I wish I had, but my process was a little different because I had Bruce.

"There was a part of me that almost wanted to lock myself in a room alone, and if I needed to reach out to the world, then it would be the man himself. I felt very lucky I had him so close."

However, The Bear star revealed that he and Butler later bonded over their shared experiences when they worked on the film Enemies together.

White recalled: "Very early on, Austin and I spoke about process.

"I had already made my film, and obviously Austin had already made his, but he was so helpful. I wish I'd met him earlier."

Jeremy learned how to sing like Springsteen for Deliver Me From Nowhere and explained how he picked up a lot from 'The Boss', who was involved in the making of the flick and made regular visits to the set.

The Golden Globe-winning actor said: "A lot of what I learned from Bruce was in his actions and the way he moves through the world.

"Early on, I was impressed by how gentle and kind he is with the world. For a man who has been where he has for decade after decade, that's a real rarity to still be so grounded, to have so much humility, to be so available and honest - not just with me but with the world around him.

"It's a beautiful thing to see, and it gives me hope for myself and for all artists."

Meanwhile, Springsteen publicly praised Jeremy for "playing a much better-looking version of me" in the movie.

The 76-year-old singer added: "I spent my life on the road, moving around the world as kind of a musical ambassador for America, you know... trying to measure the distance between American reality, where we've often fallen short of our ideals.

"But for a lot of folks out there, she continues to be a land of hope and dreams, not of fear or divisiveness or government censorship or hatred."
