In 2005, he returned to off-Broadway theater in the premiere of Noah Haidle's Mr. Marmalade, playing the title character, an emotionally disturbed little girl's imaginary friend. 2006–2014: Television focus and Dexter Hall starred in and co-produced the Showtime television series Dexter, in which he played a psychopathic blood-spatter analyst for the Miami Metro Police Department, who moonlights as a serial killer/vigilante. Jennifer Carpenter played his adoptive sister, Debra Morgan. The series premiered on October 1, 2006, and ended its run in 2013. After months of rumors, on April 18, 2013, Showtime announced via social media that season eight would be Dexters final season. Hall also voiced Dexter Morgan in the animated web series Dexter: Early Cuts. For his work on Dexter, Hall was nominated for five Emmy Awards for Outstanding Lead Actor in a Drama Series from 2008 to 2012. The show itself was also nominated for Emmy citations in the Drama Series category in the same years. He won the 2007 Television Critics Association award for Individual Achievement in Drama.

Also in 2010, he won a Screen Actors Guild Award for Outstanding Performance by a Male Actor in a Drama Series. In 2014, Hall stated he would be open to returning for a spinoff series, but said: "I can't even wrap my mind around that. And it's all just theoretical until there is some sort of script reflecting somebody's idea of where it could possibly go. But it's hard for me to imagine what that would be. Yeah, as far as playing Dexter again for an undefined amount of time, that's a little daunting to consider. But doing another television series—there's a lot of amazing stuff on TV. I don't want to do that right away. But I wouldn't say never to that." He has said he would consider revisiting his role as the serial killer if something was written that he deemed "worth pursuing". Hall's film credits include the thriller Paycheck (2003), the science fiction thriller Gamer (2009), the 2011 drama The Trouble with Bliss (2011), the comedy Peep World (2012), and Kill Your Darlings (2013).
