Lithgow Joins “Dexter” Fourth Season

Last year it was Jimmy Smits, this year multi award-winner John Lithgow will be featured in all twelve episodes of season four of Showtime’s top-rated drama series “Dexter.”

“Dexter” stars Michael C. Hall as a complicated and conflicted blood-spatter expert for the Miami police department who moonlights as a serial killer.

Lithgow will play Walter Simmons, an unassuming, mild-mannered suburbanite who has been living a dual life as one of America’s most prolific and deadliest serial killers.

Dubbed the “Trinity Killer” because of his proclivity to kill in three’s, he relocates to Miami after being tracked by F.B.I. Special Agent Frank Lundy (Keith Carradine).

Brought on to assist in the investigation of Miami’s latest serial killer, Dexter Morgan (Michael C. Hall) becomes fascinated with “Trinity’s” unique killing methods and his ability to evade capture for almost three decades.

The new season premieres September 27th on Showtime.
