John Lithgow joins 'Dexter' cast

 In a terrific bit of casting, Showtime has hired John Lithgow to play a serial killer in the fourth season of "Dexter." 

From the release:

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. 

Lithgow is sure to be an improvement over last season's guest role from Jimmy Smits, who never seemed to really fit the show.

I'm concerned Lithgow is too old to be in any physical altercations with victims or Dexter. My recollection of "killers" is that they tend to be under 50 years old. Lithgow is how old?
