The 25-year-old actor made his first feature-length outing as Barry Allen aka The Flash in the new DC Extended Universe movie 'Justice League' - after making a brief cameo in 'Batman v Superman: Dawn of Justice'.

The DCEU creator Snyder, 51, was originally meant to helm the recent movie but the filmmaker stepped away from the latest release back in March after his daughter, Autumn, died, but Miller said he has "taken care of us all".

As part of 'Justice League: The Official Collector's Edition' - a new book full of cast and crew interviews and concept art - Miller said: "Zack Snyder is the DC god. He's the father of our universe.

"He's been directing this series of films that will really plant the seeds for the whole Gaia tree of the DC Universe, and its many branches and flowers, giving us, the cast, this template as an artistic community.

"Zack has really taken care of us all. He's been so incredibly attentive to all of us and our diva needs and our questions.

"And when I want to overthink the physics of The Flash, he's been ready to engage with me on that level."

After stepping away from 'Justice League', Snyder was replaced by 'Avengers' helmer Joss Whedon and Miller's co-star Henry Cavill - who plays Superman - said he shared the same vision with the new director.

The 34-year-old actor recently said: "I've always enjoyed the traditional, very classic view on Superman in the comic books. I think there's an enormous complexity to that character.

"I know when I was working with Joss, he and I saw eye-to-eye on some of the aspects of Superman. That paragon of hope. That ideal.

"That wonderful feeling of, 'Oh, good Superman's here.' I have also developed a very personal and protective relationship over this character, and it was just lovely to have the opportunity to smile and feel good."

'Justice League' focuses on Ben Affleck as Batman, Gal Gadot as Wonder Woman, Miller as The Flash, Jason Momoa as Aquaman and Ray Fisher as Cyborg, who must come together to protect Earth from the alien threat of Steppenwolf.
