Cooper Koch responds to a possible return as Erik Menendez in potential bonus episodes for Monsters: The Lyle and Erik Menendez Story. Following the season 2 release of Ryan Murphys true-crime anthology show, Los Angeles District Attorney George Gascn announced a new court hearing for the real-life Menendez brothers. Upon learning of the news, Murphy revealed his interest in potentially returning to the brothers story for one, or two, potential bonus episodes. While he wants to see how this story ends because this story is not over, he also noted that the episodes would only happen if both Koch and Nicholas Alexander Chavez were interested in reprising their roles.
