Angelina Jolie is a certified Hollywood A-lister. She might not have appeared in as many movies in the 2010s as she did in the 2000s, but Jolie's early work cemented her status as one of the best in the business. So, when she says that Marvel's Eternals is "certainly the biggest thing" that she has ever worked on, it's no small praise.

As a matter of fact, the Hollywood actress, who won an Academy Award for her role in 1999's Girl, Interrupted, just revealed her training regimen to prepare for her role as Thena for the upcoming MCU movie.

What kind of training did Jolie undergo to prepare for Eternals?

Jolie is no stranger to starring in action films. After gaining prominence in the late 90s and early 2000s, Jolie starred in iconic action movies like 2001's Tomb Raider, where she took on the role of Lara Croft.

Although the film isn't fondly remembered as one of the best video game film adaptations of all time, it was good enough to get a sequel in 2003. In total, Jolie's time as Lara Croft saw box office returns of $400 million. Not too shabby at all.
