Being Charlie executive producer Douglas Shaffer opened up about Nick Reiner's behavior on set of the 2015 film, claiming he seemed like a "gentle guy." In a new interview with People published on Thursday, December 18, Shaffer recalled his experience with Reiner, 32, at the time, noting that nothing seemed amiss with his demeanour at the time. "From my interactions with Nick, he seemed like a gentle guy," Shaffer told the outlet. Nick, who battled addiction and entered rehab from age 15 onwards 17 times before the film was released, cowrote Being Charlie, inspired by his struggles.
