For the purposes of this discussion, Prime Time is from 7 to 11PM (Eastern) and I’m only interested in scripted live-action dramas or comedies, and people who are main characters (for the purposes of this discussion, a main character is one one appearing in 90% or more of episodes in a television season (since main character status is usually contracted on a seasonal basis, I won’t worry about people who have been demoted from “main” or achieved “main” midway through a season). And I’m only interested in successful series, which for the purposes of this discussion means “had 3 or more seasons.” (but the character doesn’t have to be in all of the seasons).
Who is the person who has been a main character in the most successful series?
Who is the person who has been a main character in the most seasons of a successful series?
Who is the person who has been a main character in the most episodes of a successful series?
I think top contenders include Lucille Ball (three successful series, with lots of seasons and episodes), William Shatner (three successful series, etc.), William Conrad, and Kelsey Grammer, but I’m no doubt missing people.
Sam Waterson has been in 397/488 episodes of Law & Order and S. Epatha Merkerson is on his heels with 391 episodes (although 2 of them she was a different character). Waterson is still going.
Dick Van Dyke: 158 (The Dick Van Dyke Show) + 72 (The New Dick Van Dyke Show) + 178 (Diagnosis: Murder) episodes over 5 + 3 + 8 seasons, respectively. Plus 5 D:M TV movies and the series’ backdoor pilot.
