'Dexter' season 8 will receive an early premiere on June 30 this year to help Showtime launch its newest drama 'Ray Donovan,' so the casting goodies of what could turn out to be the Showtime serial killer drama's final season have been fast and furious. The latest on the table for 'Dexter' season 8 is that of now-cancelled 'Last Resort' star Darri Ingolfsson, but will he prove friend or foe to the Bay Harbor Butcher?

Dexter Morgan has always had a bit of trouble with his neighbors, and that doesn't look to change as the Showtime drama heads into its eighth and potentially final season. Entertainment Weekly reports that actor Darri Ingolfsson is the latest to sign up for Dexter Morgan's likely swan song, taking the role of a medieval antique dealer who starts dating Dexter’s neighbor across a multi-episode arc. Shocking, we know.

Whether or not CBS head honcho Les Moonves' comments about a final season prove true, ‘Dexter’ season 8 will feature appearances from ‘Entourage‘s’ Rhys Coiro as a bail jumper on Deb’s radar, ‘The Walking Dead‘ star Nick Gomez as a hitman that comes to tangle with Deb, Charlotte Rampling as criminal profiling neuro-psychiatrist Dr. Evelyn Vogel, and ‘The Boondock Saints’ star Sean Patrick Flanery as ex-cop turned private-eye Jacob Elroy.

Well, what say you? Are you interested to see what secrets Darri Ingolfsson's character might be hiding? Could ‘Dexter’ season 8 be the final year for the series? Give us your predictions for the June 30 premiere in the comments!
