Two of Dexter Morgan’s greatest adversaries are returning forDexter: Resurrection. Jimmy Smits and John Lithgow are set to reprise their respective roles as Miguel Prado and Arthur Mitchell aka the Trinity Killer despite the fact that both of them were killed off in the originalDexterseries.

Deadinebroke the news about Smits and Lithgow’s respective returns. This will mark the second time that Lithgow has come back to the franchise after appearing inDexter: New Blood. Lithgow had a co-starring role in last year’sConclaveand he wasrecently cast as Dumbledorein HBO’s upcomingHarry Potter series. Smits has a long list of dramatic credits to his name, includingNYPD Blue,L.A. Law,The West Wing, andSons of Anarchy. He has also played Bail Organa in the Star Wars universe for over two decades, with appearances inObi-Wan KenobiandRogue One: A Star Wars Story.

In the third season ofDexter, Smits’ character was a district attorney who befriended Dexter and shared some of his appetite for murder. When Miguel went too far with his murders, Dexter was forced to kill him. Lithgow’s Trinity Killer was initially admired by Dexter for being able to pull off his double life as a serial killer and a family man. But once Trinity and Dexter began hunting each other, the former made the latter regret not killing him sooner by murdering Dexter’s wife, Rita, and leaving their infant son, Harrison, covered in blood.

Presumably Smits and Lithgow will either appear in flashbacks or as visions in Dexter’s present. Dexter has been no stranger to hallucinating the dead before, as seen by his frequent conversations with his late adoptive father, Harry Morgan (James Remar).

As revealed in the first episode ofDexter: Original Sin, Dexter (Michael C. Hall) survived being shot by his son, Harrison (Jack Alcott), and both will return forDexter: Resurrection. Remar will also be back as Harry, and so will David Zayas as Detective Angel Batista. However, Jennifer Carpenter recently confirmed thatshe will not reprise her roleas Dexter’s late sister, Debra.

Earlier this year,Uma Thurman joined the castofDexter: Resurrectionas a woman named Charley. Peter Dinklage is also set to co-star on the show as Leon Prater, with Neil Patrick Harris as Lowell, Krysten Ritter as Mia Lapierre, Eric Stonestreet as Al, and David Dastmalchian as Gareth.

Dexter: Resurrectionis expected to premiere on Showtime later this year.
