Chris Hemsworth has likened playing Formula One champion James Hunt in Rush to playing superhero Thor.
Lauda survived a catastrophic crash in Germany in the middle of the season, which almost killed him. But just weeks later he was back on the track challenging English rival Hunt again.
Chris said of comparing the role to that of comic book hero Thor: "It's a little different and little similar in odd ways.
"I guess, playing a real-life character, there's a huge responsibility and weight on your shoulders to do that person justice and memory of that person.
"And then I guess Thor, he's not a real person as such, but he had a huge following of people for 60 years who knew much more about him than I did. So in a way they were both daunting."
Lauda, portrayed by Daniel in the film, and writer Peter Morgan were also on the red carpet.
Daniel revealed that making the movie got him addicted to the thrill of driving fast cars. The German actor said: "After one lap, I totally got the addiction because it's pure addiction. The whole car vibrates through your body. I see totally why young guys want to become a race driver."
