“Fringe” and “Sleepy Hollow” alum John Noble will join “Elementary” season four as a series regular, CBS announced Wednesday.

Noble will play the wealthy, estranged father of Jonny Lee Miller’s Sherlock Holmes in the crime drama. The character has been referenced in past seasons as being instrumental in Sherlock’s first stint in rehab three years ago and in pairing his son with Joan Watson (Lucy Liu), his former sober companion-turned-investigative partner and friend. In the season-four premiere, airing this fall, Mr. Holmes arrives in New York City to deal with the aftermath of his son’s recent relapse.

“We could not be more delighted to have John Noble taking on such an important role,” said “Elementary” creator Robert Doherty. “We’ve enjoyed his work for many years now — especially his tremendous run on ‘Fringe’ — and cannot wait to see him opposite Jonny and Lucy. It’s going to be an exciting season.”

In addition to his regular roles on “Sleepy” and “Fringe,” Noble has made guest appearances on “The Good Wife,” “Forever” and “24.” On the bigscreen, he is perhaps best known for playing Denethor in Peter Jackson’s “Lord of the Rings: The Two Towers” and “Lord of the Rings: The Return of the King.”

“Elementary” also stars Aidan Quinn and Jon Michael Hill. The drama hails from CBS Television Studios with Doherty, Carl Beverly, Sarah Timberman, John Polson and Jason Tracey serving as executive producers.
