Chlo Sevigny is sharing just how intimidating her American Psycho co-star was on set.

The actor recently sat down with Vanity Fair to discuss the 2000 film, in which Christian Bale played a murderous investment banker with a commitment shed never seen before. While his method acting has since become legend, Sevigny found it challenging on set.

I was really intimidated by his process and intimidated by him, she told the outlet. And I wanted a little more generosity to make myself feel more at ease, which is my own ego. It was a really challenging dynamic for me, but I dont think that I thought he was bad.

I was just kind of confused, like, Why arent you being social? Sevigny continued.

Sevigny was 25 years old when she was cast in the controversial adaptation of Bret Easton Ellis novel and wasnt even aware of method acting a technique Bale used to fully immerse himself in the icy role. She took a fake it until you make it approach herself, she said.

The source material itself was famously protested at the time of its 1991 publication due to the relentless racism, misogyny and sexual violence of its protagonist Patrick Bateman. While Bale brilliantly mined the nihilism of his character, not everyone saw his vision on set.

I actually truly remember thinking that Christian Bale was terrible, co-star Josh Lucas told the outlet. I remember the first scene I did with him, I watched him and he seemed so false and I now realize that it was this just fucking brilliant choice that he was making.
