Who Is Playing Erik Menendez in Netflix’s ‘Monsters’? 5 Things to Know About Cooper Koch

Cooper Koch is the breakout star of Ryan Murphy ’s Monsters: The Lyle and Erik Menendez Story .

Koch had a few roles under his belt before taking on Erik Menéndez , one of the two brothers who infamously murdered their parents, Kitty and José Menéndez , in 1989. The actor called the role a “dream come true” while speaking with Entertainment Tonight ahead of Monsters’ September premiere. “I am pinching myself right now, I am so grateful to be here. I could cry.”

Koch said that the clothes and show’s set transporting him back to the 1990s really allowed him to get into character.

“I turned my trailer into Erik’s room, so I had clothes everywhere, and I had pictures of him on the wall, pictures of me too,” Koch told The Wrap in a separate interview. “I listened to [Erik] and watched him religiously. And I had my music, I had all different kinds of journals, all different kinds of things to help me really feel like him and be him.”

The real Erik is in prison, along with brother Lyle Menéndez , after they were convicted in 1996. The siblings alleged that they experienced sexual assault at the hands of their father.
