“Every actor dreams of doing a period piece,” he said. “There’s a lot of information [about Lyle] and also a lot of information we don’t have. That’s your job as an artist [to fill in the gaps].”

“It’schanged everything about me,” Chavez told PEOPLE of his time on the iconic ABC series. “Before the show, I was selling cars in Florida. This show has given me the gift few people get in life — the privilege to earn an income doing what I love to do every single day.”

Nathan Laneplays investigative journalist Dominick Dunne, who covered the Menendez trial forVanity Fairin the ’90s. Dominick was also one of two reporters granted full access to theO.J. Simpson trialin 1995. He died in 2009 at age 83.

According to Dominick’s son, actor Griffin Dunne, he was “not a terribly unbiased” reporter. “During O.J., he sat with the Browns and Nicole’s family …he always looked at it from the rights of the victim,” Griffin told PEOPLE in June 2024.

At the time of the murders, Lane was in his early thirties and just getting his acting career off the ground.

“I can’t say that I followed it all that closely, but once you start to look at either the court testimony or all the other research about what went on in their household, it’s pretty disturbing,” he toldThe Hollywood Reporter.

“I think it was easy for people in the beginning to think these two spoiled rich kids will kill their parents for the money, for the inheritance, but it’s much more complicated,” Lane continued. “It doesn’t change the fact that they committed this horrific act, but I think maybe you start to understand what led to that.”

Lane has been married to his husband,Devlin Elliot, since 2015. He’s best known for voicing Timon in 1994’sThe Lion King, and most recently, playing Teddy Dimas inOnly Murders in the Building.
