A podcast interview featuring Rob Reiner and his son Nick Reiner has resurfaced in light of Nick's arrest in connection to his dad and mom Michele Singer Reiner's deaths. Rob and Nick appeared on Paul Mecurio's "2 Chairs and a Microphone" in 2016. During a lengthy discussion with Rob, the host brought up his and Nick's 2015 movie Being Charlie. About 20 minutes into the conversation, Rob invited Nick onto the podcast since the film - starring Cary Elwes and Nick Robinson - was cowritten by Nick and based on his addiction struggles. "I think I'm lucky in the sense that I have parents that care about me," Nick said. "Because of that, when I would go out and do things like drugs and stuff like that, I'd feel a tremendous amount of guilt." He added, "I'd think, 'They're thinking about me right now. They want me to do good.' ... Some people don't have parents that have any interest in them." What Rob Reiner's Son Nick Said About Addiction, Their Complex Relationship Nick's addiction struggles started when he was a teenager; he checked into rehab for the first time when he was 15. Following several relapses and attempts at staying clean, Nick revealed he was homeless for a period of time. He penned Being Charlie during one of his stints in treatment. . "[What] he just said really got me, which is that deep down he trusted that we loved him and that we were there for him," Rob told his son on the podcast. "I think that's where we made the mistake. We didn't trust that he had that in him." Rob shared Nick, now 32, with Michele, whom he married in 1989. The late couple were also parents of son Jake, 34, and daughter Romy, 28, and adopted daughter Tracy during his past marriage to the late Penny Marshall.

Us Weekly confirmed the following day that Nick was taken into police custody on a murder charge following the deaths of his parents. He is currently being held without bail. During the resurfaced podcast episode, Nick further discussed how growing up in a famous family contributed to his addiction struggles. "I don't think this is any different than most people going through their teenage years, but I think that I had no identity and I had no passions," he explained. "I have a famous dad and a famous grandpa and that fame sort of informs who you are so I wanted to etch out my own identity with a more rebellious angry drug-addicted sort of persona." Rob Reiner's Son Nick Held Without Bail, Police Reveal in New Statement Nick explained there was a "level of self-medication" with his drug use. "There was also a level of doing something radical and doing something to get outside of myself and comfort zone," he continued, noting that being in and out of rehab centers made him feel less alone. "There's other people out here that suffer from [addiction] and they're willing to talk about it," Nick explained. "That's why, I think, we did this movie, because we feel it's important to be upfront about this sort of stuff." While both Rob and Nick admitted there was some discourse between them when making the movie, it really was a collaborative process. "I told him many times he's the heart and soul of the film and he would have better insights as to what [main character] Charlie was experiencing than I would," Rob said. "I would defer to him."
