Furthermore, it sounds like Herriman already shot scenes as Manson in the Netflix series last month, having been cast in Mindhunter earlier than today’s announcement.
There has been no release date set for the second season of Mindhunter, meaning it’s too early to tell whether or not we will see Herriman as Manson on the big screen before he heads behind bars on the Netflix series.
In Mindhunter, two FBI agents (Jonathan Groff & Holt McCallany) set out on a sinister investigative odyssey to discover the brutal answers.
Sources told the outlet that while Herriman will be playing a 1969-era Manson in Once Upon a Time in Hollywood, fans of Mindhunter will be seeing him play a 1980s version after Manson had already been locked up.
