Charlize Theron Struggled With Depression After Gaining 22kgs For Her Latest Role

The actress on how her dramatic transformation affected her

Charlize Theron is no stranger to transforming herself for her movie roles.

The 42-year-old won an Oscar for her transformative role in the 2003 film Monster where she famously gained weight and underwent a make-under, adding prosthetic teeth and even eyelids to look more like serial killer Aileen Wuornos.

Now Theron has spoken about another transformation, this time for her upcoming film Tully. In it, Theron plays Marlo, a mother of three whose brother gifts her the support of a night nanny named Tully.

"I gained closed to 50 pounds [22kgs] for this film," Theron told ET.

While it sounds like a dream for some to be able to eat whatever you want whenever you want Theron said the dramatic transformation took a toll on her, and not just physically but mentally.

"I just I wanted to feel what this woman felt, and I think that was a way for me to get closer to her and get into that mindset. You know, it was a huge surprise to me. I got hit in the face pretty hard with depression.

"For the first time in my life I was eating so much processed foods and I drank way too much sugar. I was not that fun to be around on this film."

Theron said she relied on burgers and milkshakes, but after the first three weeks the fun of having burgers for breakfast started to wear thin.

"I would literally wake up at two in the morning and I'd have a cup of cold macaroni and cheese just next to me... I would wake up and I would just eat it... I would just like, shove it in my throat. It's hard to maintain that weight."

When Theron needed to lose weight after Monster she told ET "I just didn't snack for five days," but this time around it took a year and a half to lose the weight.

"Your body at 27 is a little different than your body at 43," she said. Still, Theron made sure to lose weight in a healthy manner with the support of her doctor.

Like her performance in Monster, it's not all about the performance and Theron is set to deliver a striking portray of the struggles of parenthood.

"What's beautiful about this film," Theron explained, "it's unifying. It makes you realise that nobody has it easier than you or they don't experience any of those things. It's messy."

Tully is scheduled to release in cinemas May 10.
