Nick Reiner, 32, is allegedly a person of interest in the Brentwood homicide of his parents, Rob and Michele Reiner. This revelation echoes a decade-old film about their struggles with addiction, “Being Charlie.” The movie portrayed the harsh realities of a family torn apart by substance abuse. As Nick co-wrote the script and his father directed, it revealed a complex relationship between them. While they claimed to have closed the chapter on their issues, experts note that the gap between how the film’s creators presented their story and reality was significant.
