Netflix's 'Mindhunter' was a critical smash when arrived on the streaming service last year and the follow-up season has been hotly anticipated - but, sadly, details have been light on what precisely the next season will be about.

David Fincher previously said that the season will be largely set during the Atlanta Child Murders investigation, however a recent report by That Hashtag Show is now claiming that the interview format will also be used and that casting is currently underway for a number of serial killer interviewees. A casting call has reportedly gone out for Charles Manson and Dave 'Son Of Sam' Berkowitz, who'll presumably be interviewed by Tench and Ford in the upcoming season.

As well as this, Paul Bateson - who appeared briefly in 'The Exorcist' and was later the inspiration of Friedkin's later film, 'Cruising' - is also understood to feature along with Wayne Williams, the man who was eventually apprehended for murdering two men in Atlanta and believed by local police to be the serial killer responsible for the Atlanta Child Murders. Williams, who's still alive, has maintained his innocence and claimed that the Atlanta Police Department covered up evidence of KKK involvement in order to prevent a race war breaking out in the city.

Former FBI agent John E. Douglas, who wrote the source book that 'Mindhunter' is based on, stated he believes Williams was responsible for the death of at least eleven young men in Atlanta, but claimed that there was "no strong evidence linking him to all or even most of the deaths and disappearances of children in that city between 1979 and 1981."

No release date has been set for the second season of 'Mindhunter'.
