Name some actors who have starred in 3 successful TV series

Name some actors or actresses who have starred in at least 3 (reasonably) successful TV series

The rules[list=1][li]Each series must have lasted at least 80 episodes (about 3 or 4 seasons)[sup]1[/sup] on U.S. primetime network television[/li][li]The actor must have played a major character on the series for at least 3 seasons (but not necessarily for the entire run of the series).[/li][li]No actor gets credit for playing the same character in a second series[/li][li]Playing the voice of a major character counts (Dan Castellaneta as Homer Simpson counts, but William Conrad as the narrator of “Buck Rogers” doesn’t) [/list=1]I can think of only a few who (probably) fit the bill:[/li]
Michael Landon: Bonanza, Little House on the Prairie, Highway to Heaven
Lee Majors The Big Valley, The Six Million Dollar Man, The Fall Guy
Heather Locklear: Dynasty, T. J. Hooker, Melrose Place (and Spin City if she stays on the show a total of 3 years)
Bill Cosby: I Spy, The Cosby Show, Cosby
Kate Jackson: The Rookies, Charlie’s Angels, Scarecrow and Mrs. King (I’m not sure she was a major character in “The Rookies”. I don’t think I’ve ever seen the show).

Surely there are others. Aren’t there? It kept me up for a couple of hours last night trying to think of some, but these five were the only ones I could come up with. There is no shortage of people who have starred in two successful series.

[sub][sup]1[/sup] I lowered the standard from 100 episodes to 80 episodes specifically to let Bill Cosby slip under the wire.[/sub]

Majel Barrett. She does the voices for the ships computers in the three latter-year Star Trek series. Not exactly a “starring character”, but a crucially prominent one.

I think, nowadays, most actors are chosen not so much for their diversity, but because they fit the role. Typecasting seems much more common these days than it was forty years ago… and while, then, it was seen as something to avoid, now it seems to be considered beneficial to a career (if you’re successful enough to be typecasted… cha-ching!).

William Shatner in (of course) Star Trek and TJ Hooker and y’know, that other one…umm…

RATS! I wanted to say Kelsey Grammar for Cheers, Frasier and Sideshow Bob. But the first two are the same character.

Are you thinking of “Rescue 911”? I had completely forgotten about that. It’s not exactly what I had in mind, but I guess it does qualify.

Harry Morgan
Pete and Gladys

Can we count Jane Curtain for SNL, Kate & Allie, and Third Rock?

Carroll O’Connor:

All in the Family
Archie Bunker’s Place
In the Heat of the Night
Shatner was also in "Barbary Coast, but I doubt that went to 80 episodes

James Garner?
Rockford Files

 I think he was in another series, but can't think of one

Bill Cosby has had a LOT more than 3 series:

I Spy
 The Cosby Show (he played a high school atheltic instructor)
   The Cosby Show (a variety show. It featured one of the last TV appearances of Groucho Marx)
     The Cosby Show (Dr. Huxtable)
       The Cosby Mysteries
         The Cosby Show (the one where he's a retiree)
            Little Bill
              Fat Albert

Betty White:
“The Betty White Show” (1950s)
“The Mary Tyler Moore Show” (1970s)
“Golden Girls” (1990s)

Bob Newhart:

The Bob Newhart Show

I’m sure David Hasselhof(sp?) must have been in something besides Night Rider and Baywatch. Don’t know what though.

Bill Bixby:
My Favorite Martian
The Courtship of Eddie’s Father
The Incredible Hulk

do you want to open the floodgates and include game show hosts, too?

[nitpick alert](by the way Carrol O’Connor wouldn’t count under the rules, since the character of Archie Bunker was the same for both AB’s place and AITF).[/nitpick alert]

I was thinking of him, but I don’t think Bob meets the 80 episode criterium.

How about Ted Knight? He had at least two. If I was at home, I could consult a couple of books I have and I’m sure we’d discover even more.

Neither did Star Trek - 68 eps.

He played the same character in the first two shows, so I don’t think it counts.

Markie Post was in three series that each lasted at least three seasons (Night Court, The Fall Guy, and Hearts Afire)

Howie Mandel has been in three series that each lasted three seasons, but the last two were cartoons (St. Elsewhere, Muppet Babies (he did the voices of Animal, Bunsen and Skeeter), and Bobby’s World.

I’m not sure if his frequent appearances in “Matlock” count, but he was certainly in both “Andy Griffith Show” and “Three’s Company”.

Also, not sure about the longevity of “The New Dick Van Dyke Show”, but pair that with the original, and “Diagnosis Murder”.

Hmm, this is harder than i thought!

Ok, this one for sure:

William Daniels: “St. Elsewhere”, “Boy Meets World”, and “Knight Rider”!

William Daniels also starred in the series “Captain Nice” in the early 1960s

Does Lucille Ball count?

I Love Lucy
The Lucy Show
Here’s Lucy

Basically the same character, just different last names.

Aside from the fact that “Bob” only ran a season, you really can’t even give him credit for two series, as he played the same character in both, though granted, the bulk of “newhart” was a vast and elaborate dream sequence…
