Charlotte Rampling and Sean Patrick Flanery have just lined up a couple of killer new roles.

In a rare television role, British actress Rampling will play a neuro-psychiatrist who works with young psychopaths and uses unorthodox methods in profiling criminals.

Flanery will play a former police officer named Jacob Elroy who currently runs a Miami private-investigation firm.

"Dexter," which wrapped up its seventh season in December (and hit a ratings record for a Showtime original series with the season finale), will make an early return, premiering its eighth season on June 30 as a lead-in to the new Showtime series "Ray Donovan."

News of Flanery's casting was first reported by Deadline; EW.com initially reported Rampling's casting.
