Ever since making her breakthrough in The Princess Diaries, Anne Hathaway has proven time and again that she is willing to give each and every role everything she has.

An adept character actress, Hathaway is never one to shy away from fully transforming herself for a role, and this often involves switching up her hair 'do.    

This week, Hathaway debuted one of her boldest looks to date while filming her latest movie The Last Thing He Wanted, based on Joan Didion's award-winning novel of the same name.    

The Oceans 8 star was photographed on set with fiery red hair, and it's a shade we've never seen on her before.    

Hathaway's most recent dye job comes not too long after she rocked a coppery hue at Paris Fashion Week in September.

Later that month, she attended the Human Rights Campaign National Dinner while sporting a reddish-brown color.

In the past, the 36-year-old has swapped her iconic brunette locks for drastic shades and styles for her roles, including shaving all her hair off to portray Fantine in the 2012 film Les Miserables.

"It was something I've wanted to do for a long time, and I knew it was something the character did, so I just offered it to the director and he said "˜Yes.' As it got closer, I thought: I can't really take it back now," Hathaway said in an interview on Live! with Kelly at the time.

Hathaway admitted that even though it was something she had wanted to do, the process was a lot harder than she expected.

"I've now done back-flips out of windows, I've jumped off buildings, and cutting my hair reduced me to, like, mental patient-level crying," Hathaway explained. "I was inconsolable."

We're sure going red was a much less stressful ordeal than chopping off her hair, and it suits her really well.

Who knows, maybe she will be joining the ranks of other Hollywood actresses, like Emma Stone and Amy Adams, who have permanently traded their natural colors for red.
