Cooper Koch is quickly rising to prominence thanks to his latest role in Netflix’s anthology series Monsters: The Lyle an Erik Menendez Story. The Los Angeles-born actor plays the role of Erik Menéndez, one of the two Menéndez brothers convicted of killing their parents in 1989. Cooper got into character by delving into Erik’s personal life, which the Netflix star opened up about during a new interview. And since he’s only been seen in a handful of projects, fans want to know more about Cooper aside from his impressive performance as Erik.

Hollywood Life has rounded up five facts about Cooper, below!

Cooper Plays Erik Menendez in ‘Monsters’

While speaking with TheWrap in an interview published in September 2024, Cooper explained how he managed to step into his character’s shoes.

“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,” Cooper pointed out. “I looked at videos of me when I was really young, and I watched how my parents treated me, which gave me a level of gratitude for my family and my parents. 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.”

This show brought renewed attention to the Menendez brothers’ case along with new evidence found. On October 24, 2024, during a press conference, Los Angeles District Attorney George Gascón recommended resentencing for Lyle and Erik, with the possibility of immediate parole, pending a judge’s final decision. Following this news, Cooper released a statement through his brother Payton Koch on Instagram Stories, as he does not have social media. The statement read, “I am overwhelmed with gratitude and hope for the progress we’ve seen today. Gascón’s recommendation has ignited a renewed sense of possibility that Lyle and Erik could finally be released after decades behind bars. But, this journey is not over.”

He continued,“There are still critical steps ahead: the judge must endorse the resentencing, and, if that happens, the parole board must recognize the time they have served as fitting for the crime. Our voices, our unwavering support, remain crucial-not just for the brothers to ensure their release, but also for every victim of sexual abuse fighting to be heard. I hope to see Erik and Lyle soon. Free from all of this.”
