The Oscar-winning celebrity, 45, said learning and training about the dangerous task left her feeling motivated.
"To research it with the manager [Taylor Sheridan] that really knows and loves this part of earth and also to get to know the firefighters, the smoke jumpers, the survivalists, the people which are in this section of America and to spend some time together and try to do our very best to represent them on movie -- a massive amount of respect for them," Jolie told Fox News while boosting the film.
"I feel every project comes with this whole new sort of introduction to [a] world," he told Fox News. "I think human beings are tremendously fascinating and spend time in anybody else's world and try to explore the nooks and crannies of it... it's a real chance; [a] real honour."
Jolie's character is coping with some previous injury and stated she discovered those psychological nuances really deep and it made her attracted to the role.
"I do I love action. I really like a thriller. I love all of that. But if you are unfamiliar with the characters and you do not feel like you're actually following, you knowa person story and relating or caring about those characters, then and it's inadequate," she explained.
Jolie also spoke about working with her young co-star, Finn Little.
"Usually, I am in my own when I do a lot of this [stunt] work or with a different adult. So to be with somebody who's younger, just to be aware of where he is at all times. But you know, he was so tough," she recalled.
"But he helped me evenly. So we actually found a partnership and it turned into much more fun to do stunts collectively," Jolie added.
"Those Who Wish Me Dead" is now available to flow on HBO Max and in select theatres.
