Giancarlo Esposito thinks that 'Megalopolis' will change the movie industry.

The 'Better Call Saul' actor features in the all-star cast of Francis Ford Coppola's epic new sci-fi drama and is certain that the picture will have a lasting impact on how directors work.

Giancarlo told The Hollywood Reporter: "It is just a brilliant and beautiful film.

"I don't want to just qualify it as an art film because I think it's a film that's progressively different and will change the way (many) filmmakers look at filmmaking.

"The elements that he put in the film – like the live onstage moment that happens in interaction with the film – is something that is never been done before."

Coppola has spent decades developing the movie – which is scheduled for release in September – and Giancarlo is delighted that 'The Godfather' director's persistence has finally paid off.

The 66-year-old star said: "He taught me how to be courageous. He taught me to not ever give up, keep following through and put your money where your mouth is; have skin in the game."

'Megalopolis' tells the story of how an architect (played by Adam Driver) tries to rebuild the city of New Rome following a disaster as he clashes with corrupt mayor Franklyn Cicero (Esposito) and Giancarlo was reduced to tears by the "strong message" that is communicated in the movie after seeing it for the first time at the Cannes Film Festival in May.

He recalled: "I sat a seat away from Francis in Cannes and I had tears in my eyes at the end of the movie, because I feel like the film has a strong message. It says something about how we think and how we live, and it encourages people to open their brains to think progressively about our world. That large of a message, it's visionary.

"As an actor, I work so deeply and do so much homework to be prepared, but I have to remember to let it go and play sometimes. I was reminded of that on this film."
