Well, now we're back with even more...along with movie/TV makeovers actors actually loved!

BRUTAL: Hugh Jackman lost a ton of weight for "Les Misrables" especially that opening scene, when his character is released from prison.

Jackman revealed he wouldn't even drink water during that part of filming until super late in the day. You lose up to 10 pounds of water weight, mainly from the exterior of the body. But it was really brutal," he explained. "About 20 hours in, a headache came. Then I wanted to drink water out of the ocean! I see the scene now, and I look really thin, really sunken.

BELOVED: Charlize Theron famously went bald for her iconic role as Furiosa in "Mad Max: Fury Road." It was actually her idea she said her hair was "fried" from a press tour, and she suggested Furiosa have a shaved head.

Theron called her new cut "great," and emphasized how convenient it was. After that, I was 20 minutes early to everything in my life, she said. It was unbelievable, like how much time we spend on our hair. And then also, I think I emptied two garbage bags full of hair products and brushes. Theres something very freeing in that, for sure, definitely. And theres always something nice when you kind of take that importance of your femininity and make it about something more than just your hair.

BRUTAL: Miley Cyrus was not fond of getting dolled up in glitter and a blonde wig for "Hannah Montana." "From the time I was 11, it was, 'You're a pop star! That means you have to be blonde, and you have to have long hair, and you have to put on some glittery tight thing.'" Cyrus told Marie Claire magazine.

"Meanwhile, I'm this fragile little girl playing a 16-year-old in a wig and a ton of makeup. It was like 'Toddlers & Tiaras.' I had fucking flippers." She said that being made to look like someone she wasn't "probably caused some body dysmorphia" because she was "made pretty" for so many years that when it ended, she didn't know who she was.

BELOVED: Like Theron, Natalie Portman also shaved her head for a role in her case, "V for Vendetta." This isn't confirmed, but according to IMDb, she'd actually been wanting to shave her head for a while.

Speaking about cutting her hair, she did say, "It was actually kind of wonderful to throw vanity away for a little bit as a woman. You know, you're always expected to be primping and preening yourself. It's a pretty nice opportunity to get to not think about that stuff for a little."

BRUTAL: Christian Bale is particularly famous for transforming himself for roles especially for his role in "The Machinist."

Playing an emaciated insomniac in the film, Bale had to lose over 60 pounds. He did so by basically subsisting on a diet of cigarettes and whiskey. He later said the only other things he consumed were an apple, a tin of tuna, and black coffee about 200 calories a day. Losing weight became an "obsession," and he said he wanted to go beyond what was "safe and OK," and wasn't thinking about his own health.

BRUTAL, AGAIN: Another miserable transformation Bale had to undergo was to transform into Irving Rosenfeld for "American Hustle." In addition to gaining 43 pounds and shaving his head so he could glue on a toupee, he also took to slouching in every scene to better portray the character. In fact, he did this so much, he herniated a disc in his back.

BELOVED: For his role as Archie Andrews in "Riverdale," KJ Apa had to dye his normally brunette locks red. The process took eight hours in a salon, and has to be touched up every two weeks. "It was gnarly," he said, also mentioning how he doesn't know how women do this. He said he was really nervous about how he'd look with red hair and brows.

However, Apa actually ended up liking the look. "It was definitely really weird to see," he said. "But now I can't really remember what it was like before. I heard that only 2% of the population of the world has red hair, so I'm feeling pretty good right now."

BRUTAL: For his brief role on "The Flash," Mark Hamill dyed his hair purple, for some reason opting for permanent dye.

BELOVED: For her role as Anne in "Anne with an E," Amybeth McNulty had to dye her normally-blonde locks red. She was definitely nervous, having never dyed her hair.

However, she now says she wishes she were a natural redhead. "It turned into a beautiful red so pretty. And my friends were like, 'It suits you better than your blonde hair.'

BRUTAL: Matt Bomer lost over 35 pounds to play a man dying of AIDS in "The Normal Heart."

While he was happy to do it and said it gave him a "lust for life" and strong desire to fight and live like his character, the transformation was definitely hard on him. Director Ryan Murphy said it got so bad that he was essentially too weak to move between takes, and that he cried when he saw him because he was so worried for his health.
