Gethin Anthony, who played Renly Baratheon on Game of Thrones, has been cast as Charles Manson in NBC’s forthcoming “event series” Aquarius.

Gethin Anthony Joins 'Aquarius'

As Manson, Anthony will portray the “archetypal Authentic Hippie Freak,” according to TV Line. When the series opens, Manson is a small-time jailbird who’s spent a good portion of his life behind bars. As he begins building his cult, he grabs the attention of LAPD Sgt. Sam Hodiak, played by David Duchovny.

“The twists and turns of a complicated undercover operation will lead Duchovny’s character and his young partner to the brink of Manson’s crimes that will eventually lead to the Tate-LaBianca murders in subsequent seasons,” according to NBC.

Friday Night Lights actor Grey Damon will play Duchovny’s character’s new partner, who helps him track down Emma Karn – played by Bunheads’ Emma Dumont. Emma Karn, as it turns out, is recruited by Manson, seduced with a mixture of sex and drugs, as well as fatherly protection. Damon eventually goes undercover to get a closer look at the charismatic leader.

Duchovny is executive producing Aquarius with writer John McNamara (Profit, In Plain Sight).
