Interestingly, Ryan Murphy has been trying to work Charles Manson into American Horror Story for a while now.
Collider reports that Murphy was looking into incorporating Manson into Season 7 now that we’re only a couple of years away from the 50th anniversary of the Manson family’s 1969 murder of Sharon Tate and four others.
Murphy was struggling to find a way to put a fresh twist on the Manson story; the heat of the 2016 presidential election and the powerful public personas that emerged out of the campaigns inspired Murphy to incorporate Manson as an example of an individual who rises from a group and inspires others by sheer force of personality.
