20 Actors Who Transformed Completely For A Role

Actors are masters of disguise. They literally become other people. Most of the time they’re permitted to look mostly like themselves, the symmetrically featured, good looking humans, who others love to watch on film.

When actors take on roles that are a stretch for them, it’s a big challenge. Sometimes it means transforming the way they look or act in the process. These sacrifices for a role often lead to awards and critical acclaim, leading to other game changing parts. Some actors lead their lives like chameleons subscribing to method acting, literally becoming the person they portray on screen. Some abandon this practice as they age, as it’s too hard on their bodies, or they want to focus their time on their families, where others can’t get enough of who they can become next. Here are 20 stars who completely transformed the way they look for a role and how they did it.

Rami Malik knew he had to fill larger than life platform shoes to become Freddie Mercury. To get a believable performance, not only did Malik have to wear a mouth prosthetic, he had to learn to both talk and sing with it in place. No wonder people can’t stop talking about Bohemian Rhapsody!

Wonder Woman is an Amazon Warrior, not a lithe fashion model. When Gal Gadot took on the role of Wonder Woman producers wanted to make sure that Gadot looked like she could fight. So, they put the actor on orders to bulk up and put on a lot of muscle with the same trainers as other DC leading characters have used. Her program focused on eating protein, drinking water, working out for at least an hour each day, and getting enough sleep.

Becoming a 'Monster' for the 2003 film won Charlize Theron an Oscar. The star needed to put on weight, around 30 pounds, and wear dentures to hide her Hollywood pearly whites. In the editing side of things, they used translucent washes of tattoo ink to make Theron’s normally dewy skin look rough and weathered and added the effect of making the ends of her hair look damaged and uncared for.

17 Heath Ledger Became The Joker

Method acting was said to be the key to Heath Ledger’s terrifying and brilliant performance as the Joker in The Dark Knight. The star spent a month locked up in a hotel room and his apartment to master his part, and even journaled about it and clipped items like photos of hyenas and Alex from A Clockwork Orange as inspiration for Joker. Many people say that Ledger took the role too far and that it ultimately led to his isolation and his early death. Heath won a posthumous Oscar for the part.

16 Anne Hathaway Became Fantine

In order to portray the depths of despair her Les Misérables character Fantine was going through, Anne Hathaway had to give it her everything. In addition to lopping off her trademark long chestnut hair, her life on camera, and living off little more than kale and oatmeal for weeks before filming, she banished her husband because he was making her too happy. The star told Chelsea Handler on her show, “I love him so much that I was like, ‘You’re making me happy. You’re keeping me up and I’m clawing to the sides of my life and I need to fall into a pit and you need to go, honey.’”

Being a princess is all about the hair. Just ask Disney! The transformation of Naomi Watts into everyone’s favourite princess was all about getting the 1980’s blonde tresses just right. Many actors say that once they have the makeup and hair just right it’s that much easier to become the person you’re portraying. It’s likely this is the case for Watts, whose portrayal of Lady Di was spot on.

Time was not kind to Pete Campbell, but it was to actor Vincent Kartheiser. This meant that the Mad Men crew needed to prematurely age the actor, which meant shaving and contouring his hair to look like he was balding and adding some girth to his aging belly by putting 25 pounds onto his regular frame. Kartheiser joked about shaving his hair saying, “Most of my friends were like, Dude, don’t do that, it might never come back in! But luckily I have a good head of hair.'

When you change your look for a role that makes you a star, you might be able to remain anonymous even when your film becomes a big hit. In order to become Lisbeth Salander, Mara Rooney relied heavily on make-up artist Pat McGrath who coloured and chopped her long chestnut into a pitch-black shade with a severe haircut. Next they bleached her eyebrows and added piercings, tattoos, and a ton of make-up.

Emma Stone needed to look like a pro athlete in order to be able to compete in Battle of the Sexes.

It was reported that her workout included, “walking with dumbbells, also known as heavy farmer's walks, and 300-pound hip thrusts. She could eventually deadlift up to 185 pounds and could do push-ups with 50 pounds of chains on her back.”
