This is Us is bringing iconic character actor Denis O'Hare on board as a recurring guest star for later this season, according to Entertainment Weekly.

O'Hare is perhaps best known for his work in five of the six American Horror Story seasons and for ripping the spine out of a newscaster as vampire Russell Edgington in HBO's True Blood.

O'Hare will presumably be handling quite different material on NBC's more grounded and critically acclaimed family drama, and his character "Jessie" is described only as a friend of William (Ron Cephas Jones).

In what many viewers assume was a flash-forward, William's death was recently hinted at on the show, but given the way the timeline twists and shifts throughout the series' narrative, the how and when of his demise are still unresolved, and how or if O'Hare's character is involved with William's passing can only be speculated.

O'Hare joins a long list of actors making guest appearances on This Is Us, including Gerald McRaney, Katy Sagal, Brad Garrett and Janet Montgomery.

This Is Us airs Tuesdays at 9/8c on NBC.
