DAHMER was just the beginning.

In the second installment of the Monster anthology series, Ryan Murphy and Ian Brennan tackle another high-profile case that captivated the nation in the ’90s. Streaming on Netflix now, Monsters: The Lyle and Erik Menendez Story tells the story of two brothers who killed their parents on Aug. 20, 1989, and the events surrounding the brutal slayings. (Both were convicted of first-degree murder and sentenced to life in prison without the possibility of parole.)

Created by Murphy and Brennan, the first iteration of Monster, DAHMER — Monster: The Jeffrey Dahmer Story, premiered in 2022 and chronicled Jeffrey Dahmer’s (Evan Peters) gruesome murders between 1978 and 1991. DAHMER was a record-breaking success on Netflix, reaching 1 billion view hours in its first 60 days. The 10-episode series is only one of four series, including Stranger Things and Squid Game, to achieve such a milestone. Hot off the first iteration’s success, Monster was picked up for two additional installments of following notorious figures who left their mark on society. Here’s everything you need to know about Monsters: The Lyle and Erik Menendez Story.

Nathan Lane

as Dominick Dunne

About the Character
Dominick Dunne is an investigative journalist who covers the trial for Vanity Fair.

Murphy wanted Lane for the role because he knew he could master its gravity. “I have this theory … about actors, where if you want somebody to be really, really dramatic and great, hire somebody who knows comedy,” said Murphy. “[Lane] has an amazing episode in here that I think is one of the best things [he’s] done in [his] career.”

 

Added Lane, “I just feel very lucky and grateful at this point in my life that something like this came along.”
