Dexter type TV Show network Showtime Networks Inc. Where to watch Close Streaming Options

An actor from ABC’s Last Resort has washed ashore in Dexter Morgan’s Miami.

Showtime’s Dexter has added Darri Ingolfsson for its eighth — and likely final — season.

Ingolfsson (who played a senatorial aide dating a weapons lobbyist on the ABC series) will play an antique dealer of old medieval equipment who starts dating Dexter’s (Michael C. Hall) neighbor in a multi-episode arc. That description provokes all sorts of plot possibilities, doesn’t it?

Season 8 also features guest arcs with Charlotte Rampling as a neuro-psychiatrist who specializes in working with young psychopaths and profiling criminals in unorthodox ways, and Sean Patrick Flanery as the ex-cop owner of a private investigation company. Showtime is shaking up the usual Dexter schedule, rolling out season 8 starting in the summer — June 30 — as a companion series for new drama series Ray Donovan.
