Ridley Scott on ‘Gladiator II,” Denzel Washington and Joaquin Phoenix

It’s been 24 years since the director Ridley Scott scored one of the biggest hits of his career with “Gladiator,” a swords-and-sandals epic starring Russell Crowe that won the Oscar for best picture. Now 86, Scott still works at a prodigious pace, sometimes even directing two films in the same year.

His latest is “Gladiator II,” which picks up two decades after Crowe’s character, Maximus, died heroically in the arena. In the years since, Lucius (Paul Mescal) — Maximus’s secret son — has been shuttled to North Africa where he, too, has become a capable fighter. But war waged by the Roman general Marcus Acacius (Pedro Pascal) will draw Lucius back to his birthplace, where the clever arms dealer Macrinus (Denzel Washington) will try to manipulate the young man to further his own ambitions.

In October, I met Scott at his Los Angeles office, which was decorated with posters of some of his memorable films like “Alien,” “Blade Runner” and “The Martian.” True to form, while gearing up for the Nov. 22 release of “Gladiator II,” he was already deep into preproduction for his next movie (a Bee Gees biopic set to shoot in February) and had even begun storyboarding the one after that (a sci-fi adaptation).

“I feel alive when I’m doing something at this level,” he said. “I don’t call it stress, I call it adrenaline. And a bit of adrenaline is good for you.”

Here are edited excerpts from our conversation.

A sequel to “Gladiator” had been in the works for over two decades, making it by far the longest film you’ve ever developed. What made you want to see it through?
