The film, which tells the story of a group of elite firefighters battling the devastating 2013 Yarnell Fire in Arizona, required a completely different kind of fitness to another of Brolin's upcoming movies, Deadpool 2.
“[It’s a] different shape. Totally different,” Brolin said. “Firefighting was very interior and Deadpool was very exterior.”
The actor has been sharing videos of his intense workouts on Instagram, giving a glimpse into what it takes to achieve that body.
But will he keep up the good habits now that filming is over?
“See me in two weeks and I will have fat, chipmunk cheeks,” he joked. “No, I won’t. I will keep it up because I’m almost 50, so it feels better to be in shape. I”m just a little beat up from Deadpool.”
Good thing he has Boyd around to help tend those wounds. The couple just celebrated their one-year anniversary in September, and the Oscar-nominated actor revealed how he knew she was the one.
“You go through enough relationships where you’re trying to figure it out, what does this mean, why am I so confused?” he said. “And then suddenly you’re not confused. It’s something to celebrate.”
