Lance Reddick has joined the cast of FX’s American Horror Story: Coven to play Papa Legba, mighty Loa (God) from the New Orleans and Haitian Vodou traditions. 

He acts as an intermediary between gods and humans, the gatekeeper to the spirit world. He is the keeper of all roads, intersections, doors, locks, and gates, as well as the god of travel, opportunity, and luck.

How exactly the character will be depicted in American Horror Story isn’t yet public information – other than the announcement describing him as Coven‘s version of a “voodoo Satan,” who plays a pivotal role in the life of Marie Laveau (Angela Bassett’s character on the show) and will be an important figure in the series’ remaining four episodes, when the horror anthology returns in January.

Reddick most recently joined the cast of the psychological thriller, The Guest, which follows an ex-Marine who returns from a tour of duty and is taken in by a fallen comrade’s family, who he proceeds to terrorize.

Dan Stevens plays the ex-marine.

Reddick will play a government agent aware of the ex-marine’s medical history who sets out to bring an end to his violent rampage against the family he terrorizes.

The busy Reddick can also be seen in the upcoming comedy Search Party – a film that centers on two men who travel to Mexico to save their stranded friend and reunite him with his girlfriend.

Last year, Reddick launched his own production company (Christai Films) to package high-concept projects for himself, and can currently be seen in Spike Lee’s Oldboy
