got to be two different tv series., but I would agree that Mash could be used as they Comedy or Drama one
You win with Bryan Cranston
Ted Danson: Cheers --> CSI --> The Good Place
John Lithgow - Third Rock from the Sun, Dexter
He was so creepy on Dexter that I just can't look at him the same anymore.
And A Bit of Fry and Laurie, and BlackadderHugh Laurie. House and Jeeves & Wooster.
I remember rewatching that and going "that's Hugh Laurie!"Oh, and here's a piece of trivia. He was "the Gentleman on the Plane" on the Friend's episode "The One with Ross's Wedding (Part 2)"
Alan Alda- "Mash" and "Ray Donovan".
Abe Vigoda- "Barney Miller and " Law and Order".
