Actor: John Dye
Character: Andrew, the Angel of Death
The show "Touched by an Angel" has become one of my favorites in recent months. Now bear with me- I'm still kind of a newbie to the whole thing...
Andrew is one of the angels of Death, and his job is to bring people home to God (wish I had a job that cool!). However, in the last couple seasons, Andrew has been able to do more "case-worker" stuff, like Monica.
Actor: Peter Wingfield
Character:Methos, the first immortal
Continuing with the theme of the "forever young" character, I am also a fan of the Highlander series, based on the movies featuring Christopher Lambert. A few seasons into the series, Duncan MacLeod met Methos, the first immortal. Born into immortality in the Bronze Age, he has survived for over 5,000 years. He hid for many centuries as a Watcher, the secret society that studies immortals.
Actor: Chris Noth
Character: Mike Logan, NYPD detective
From the drama "Law & Order", Mike Logan is a wise-cracking Irish-American detective. He was on the show for 5 years, investigating various murder cases. "Detective Logan" left the show after he assaulted a congressman and was transferred to Staten Island.
