Michael B. Jordan claims that playing Erik Killmonger in Black Panther took a toll on him emotionally, and he needed therapy to recover.

Kilmonger is seen as a  standout villain in the Marvel Cinematic Universe thanks to his captivating on-screen presence and the justifiable motivations behind his actions. 

But for Michael to fully embrace such an intense character, he had to go to "dark places." And it affected him psychologically.

The action hero recently admitted on The Bill Simmons podcast that it took him nearly a month and therapy to leave the character behind.

"It was one of those things that I didn't know what was going on," Michael explained. 

"I never was in a character for that long of a period of time and was, I guess, that dark, that lonely, that painful. So coming out of it, I thought, 'Oh yeah, business as usual. I can just go back home, I'll cut my hair off, and everything will be back to normal.'"

Jordan continued: "I found myself kind of in the routine of being isolated and went out of my way to make sure I was by myself and didn't say too much more than the usual. Once I got finished wrapping the movie, it took me some time to talk through how I was feeling and why I was feeling so sad and like a little bit depressed."

Actors like Michael B. Jordan who takes a more method approach, getting emotionally into the headspace of their character. And for Jordan's villainous Killmonger, it took a toll. Killmonger was a villain, but he was also someone in a great deal of pain, who had a justified sense of anger at the inequities in the world and the sins of the past. That's what made him a compelling villain, and Michael B. Jordan's approach to the character delivered on that.
