Showtime will bring back one of Dexter Morgan’s greatest enemies: John Lithgow to reprise his role as Arthur Mitchell, aka the Trinity Killer, in Dexter’s upcoming return, reportedly Deadline.
We don’t know too many details about Lithgow’s return on Dexter. The actor is expected to shoot for a day or so during production. Clyde Phillips, the showrunner of the series, and the writing team of the series They’ve found a way to bring the Trinity Killer back in a way that makes sense within Dexter’s plot.
NOTICE: Dexter spoilers
The possibility of Arthur Mitchell returning to the series is (to say the least) complicated. The Trinity Killer died at the end of season four, when Michael C. Hall’s Dexter struck him with a hammer. Although Lithgow’s presence in Dexter only lasted one season, the actor instantly became a favorite with the show’s audience.
Lithgow’s portrayal as Arthur Mitchell too was critically acclaimed. His performance earned him his fifth Emmy in 2010, beating the competition in the category of Outstanding Guest Actor in a Drama Series. Lithgow has also won Emmys for his work on Amazing Stories, 3rd Rock from the Sun, and the first season of Netflix’s The Crown. He could also get another nomination this year for his performance on HBO’s Perry Mason.
Showtime announced Dexter’s return last October. The new episodes will be set a decade after Dexter Morgan disappeared in the eye of Hurricane Laura. The season will have 10 episodes and will premiere in the fall.
