Acting is a much more complicated and difficult job than many of us would assume.

That’s because we don’t assure all the work that goes behind making a film, including all the hours performers invest in incarnating the character they’re portraying.

The best performers get into character by drill method acting, which involves doing whatever there is a need to made themselves in the character’s shoes. The main goal is to produce a sincere and emotionally expressive execution — something Charlize Theron is very familiar with.

“I wanted to feel what “womens issues” felt, and I think that was a way for me to get closer to her and get into that mindset, ” she told Entertainment Tonight, adding that she faced unexpected predicaments in the process. “You know, it was a huge surprise to me. I got hit in the face reasonably hard with hollow. Yeah, for the first time in my life I was chewing so much processed foods and I suck style too much sugar. I was not that recreation to be around on this film.”

The 42 -year-old said she had three months to gain the force, and while it was fun at first, the originality wore off pretty quickly.

“The first three weeks are always fun because you’re just like a kid in a candy store. So it was fun to go and have breakfast at In-N-Out and have two milkshakes. And then after three weeks, it’s not recreation anymore. Like, all of a sudden you’re just done eating that sum and then it becomes a job. I recollect having to set my scare in the midst of the night in order to just maintain[ the force ]. “
