'Dexter' Season 8 casts Charlotte Rampling as ...

Charlotte Rampling, a veteran British actress, has been cast in a key role for "Dexter's" eighth season, which is probably the final season for the hit Showtime drama.

EW reports that Rampling will play the recurring role of "a neuro-psychiatrist who specializes in working with young psychopaths and profiling criminals in unorthodox ways." The role will have a significant impact on the Season 8 story.

U.S. audiences probably best know Rampling from her work in Woody Allen's "Stardust Memories" or co-starring with Paul Newman in "The Verdict." She also appeared in the 2011 film "Melancholia."

"Dexter" returns early this year -- Sunday, June 30 is when the show comes back. It is being used as a lead-in for new Showtime drama "Ray Donovan," starring Liev Schreiber as a problem-solver to the rich and famous.
