We go behind the scenes of NCIS: Los Angeles to give you a sneak peek of the episode in which the real-life moms of several cast members actually guest-star alongside their famous kids!

The show’s creator Shane Brennan said the idea for the unique episode came to him when he met some of the parents on the set. After that, he said writers were tasked with creating “the perfect script and perfect episode” to bring all the moms together for the episode.

Appearing onscreen are the real-life moms of Chris O’Donnell, LL Cool J, Daniela Ruah and Eric Christian Olsen. “I thought it was a joke,” explains O’Donnell about first hearing the idea. “Mom was excited when I called her up and told her the news, and said, ‘I’m coming, I’ll be there.'”

CHEAT TWEET: #NCISLA stars real-life moms appear in the episode, 10/9, 9 pm ET/PT

“The Fifth Man” – The NCIS: LA team investigate a compromised intel operation after four people connected to the classified project are killed at a diner explosion. As Deeks and Kensi are on the trail of those involved, they learn that a wayward teenage girl might be related and Kensi can’t help but be empathetic to her situation, on NCIS: LOS ANGELES, Tuesday, Oct. 9 (9:00-10:00 PM, ET/PT) on the CBS Television Network. The real-life mothers of stars Chris O’Donnell, LL COOL J, Daniela Ruah and Eric Christian Olsen will appear in the episode alongside their children.

Without question, the Oct. 9 episode of NCIS: L.A. is the mother of all mysteries.
While the team tracks down a suspect in a casino, four women – portrayed by the lead actors’ real-life mothers – are playing poker.

When executive producer Shane Brennan e-mailed the CBS drama’s stars with the idea, “I thought it was a joke,” Chris O’Donnell says. “When I found out he was serious, I was excited to call my mom. I knew this would be the biggest deal for her.”

It was a thrill for the actors as well. “It was fun getting to work and seeing her in hair and makeup,” Eric Christian Olsen says of having his mother, Jeanne, on-set.
The producers made sure the women were welcomed in style, giving them deluxe motor coaches that surrounded a makeshift Astroturf courtyard with potted plants and patio furniture.

“It was like Yankee Stadium!” says LL Cool J.
The scene took only a couple of hours to film, but the actors say the memories will last a lifetime.

“Acting with your mom? It’s not something you get to do very often,” Daniela Ruah says.

But if O’Donnell’s mom, Julie, has her way, it will happen again soon. “She thinks this is her big break,” O’Donnell says, laughing. “If ‘Mom 2’ appears in another script I’m sure she’ll answer the call.”

And so will Ondrea Smith, LL Cool J’s mother, who admits, “I could get used to this!”
