One thing that's great about the Dexter franchise is dead characters are always welcomed back due to our darkly delusional Dexter. Jimmy Smits, who starred in season three, and John Lithgow, who starred in season four of Dexter, are returning for Dexter: Resurrection!
Emmy winners John Lithgow (Conclave, The Old Man) and Jimmy Smits (East New York, Sons of Anarchy) are set to reprise their roles of Arthur Mitchell aka the Trinity Killer and Miguel Prado, respectively, in the Showtime original series Dexter: Resurrection. The show has been in production in New York since January.
