I was thinking about actors that have played regulars on multiple TV shows over the years. With many TV actors, it seems difficult to get more than a couple series under their belt without many of them being spin-offs where the reprise their established characters.
So it seems all the more remarkable that William Shatner has now been a regular on 5 different TV shows:
1. Of course, he started as Captain Kirk on the original Star Trek.
2. Next he played the title role on the cop drama T.J. Hooker.
3. He hosted the non-fiction series Rescue 911 for several years.
4. In the 2000s, he reinvented himself as comically senile attorney Denny Crane on Boston Legal.
5. Now he's on the CBS sitcom Shit My Dad Says.
Maybe he's even up to 6 now, since he also did the reality hoax series Invasion Iowa.
That's a hell of a lot of regular TV work. So then who comes 2nd?
My guess would be Enrico Colantoni.
1. He was Gloria's ex-husband on the short-lived NBC sitcom Hope & Gloria.
2. He played the photographer Elliott on Just Shoot Me.
3. He spent 3 years as Veronica's father, private investigator Keith Mars on Veronica Mars.
4. Now he's on the CBS cop series Flashpoint.
Who else has piled up such an impressive TV resume?
