The Showtime series Dexter returns early this year, with the Season 8 Premiere debuting Sunday, June 30 at 9 PM ET, serving as a lead-in for the network's new show Ray Donovan. Dexter will be bringing in a few new faces this season, with Charlotte Rampling and Sean Patrick Flanery joining the cast.

Charlotte Rampling will be featured in a recurring role as a neuro-psychiatrist, who specializes in criminal profiling and working with demented youth. The part is said to have a "significant impact" on the Season 8 story line. Sean Patrick Flanery is also recurring as Jacob Elroy, a former Miami cop who now runs his own private investigation service.

Although it has not been confirmed by Showtime, many believe Season 8 will be Dexter's last. Will these new characters be instrumental in Dexter Morgan's downfall? We'll have to wait a few more months to find out for sure.
