Written and directed by Patty Jenkins in her feature directorial debut, filming started on February 4, 2003, when Charlize Theron was 27-years-old. Her co-star Christina Ricci turned 23 on February 12, 2003. The film was released on November 16, 2003.

For her role as real-life serial killer Aileen Wuornos, Charlize put on 30 pounds of weight.

“It wasn’t about getting fat. Aileen wasn’t fat,” Theron said in an interview with SPLICEDwire.

“Aileen carried scars on her body from her lifestyle, and if I’d gone to make this movie with my body — physically I’m very athletic — I don’t know that I would have felt the things Aileen felt with her body. It was about getting to a place where I felt closer to how Aileen was living.”

Speaking as part of a roundtable chat between producers in The Hollywood Reporter in November 2019, Charlize talked about being called out for gaining weight.

I started producing on Monster, and it just happened that I felt the need to protect a first-time director [Patty Jenkins], who was really taking a huge risk. The character was very unusual. And initially when we went in to get our financing, it became very clear to me that there was this need for me to step in.

Because I think the financiers actually thought they were basically paying for a hot lesbian movie with me and Christina Ricci. And knowing what Patty wanted to do with it, I knew that we were going to come up against things.

There were a lot of fights. As soon as I started gaining weight, I had one of the financiers call me up. Actually, his wife saw me, and she was like, ‘Did you see Charlize? Have you seen what she looks like?’ And I got that call, like, ‘What’s going on with that?’
