You first knew actor/actress from a role different from one they're widely known in.

I still have trouble watching the *Odd Couple *reboot, as Matthew Perry is NOT Felix Unger, in my mind. He’s that guy on Friends. And he has not aged well.

Jack Klugman is Felix Unger. Except when he’s Quincy, MD. Or slumming on The Twilight Zone. And my mind cannot reconcile any other paradigm at this time.

Forgive me, master*, Klugman/Perry is Oscar Madison.

*Apologies, capital M master is reserved for Cecil.

I knew and liked Kim Cattrall in Mannequin. A silly 80’s comedy.

Now shes known for Sex in the City.

Oopsie. You are of course correct. My mistake…

She was in an episode of Columbo when she was about 15. I think she got an “Introducing” for that.

Closer to 22

I am one of the few who never watched an episode of Twin Peaks. Was he good in that?

Quincy, M.E. Sorry for the nitpik.

I was surprised to see recently that he played Spider-Man on a record years ago.

He’s also always Clayton to me as well, even as Odo he seems like Clayton acting like Odo.

Morgan Freeman as Easy Reader is another one. I watched the heck out of Electric Company as a wee kid.

So this past year, my beloved turned me on to this show called Criminal Minds, in which actor Thomas Gibson plays the stony-faced yet compassionate FBI agent Aaron Hotchner.

This weirded me out, as I still remembered Gibson as the straight-laced but pleasant costar of Dharma And Greg.

And it weirded me out even worse when FBI agent Aaron Hotchner got in a fight with a seriously evil bad guy played by C. Thomas Howell, best known for his HERO roles in The Outsiders and Red Dawn…

…which, now that I think about it, made it even worse in one episode where the evil, evil, evil bad guy is in fact a rogue FBI agent, attacking them from within the organization… and he’s played by Mark Hamill, of all people…

Jack Klugman played Oscar Madison.

Tony Randall played Felix Unger.

Years before Kevin Spacey became well known for The Usual Suspects and Seven, some of us knew him as Mel Profitt on the TV series Wiseguy.

For me, Kim Catrall will always be Coach Honeywell (aka “Lassie”) in Porky’s.

Ah, I’m reminded I first saw her on Starsky and Hutch. She would have been 21 or 22 then and brunette. Starsky accidentally shot and blinded her.
Two more from As the World Turns.
Ming Na who’s on Agents of Shield (or whatever it’s called). She played Tom Hughes’ daughter.
And Thomas Gibson, playing Derek Mason, the evil husband of Lily Walsh.

There are a lot of very popular TV series that I’ve never watched, including Will and Grace, starring Eric McCormack. But I know him from a series that I and maybe five other people watched, called Lonesome Dove: The Outlaw Years, where he played a badass in the Old West.

Ooh, yeah! I can’t believe I forgot about Ming Na(-Wen) as Lien. I do remember Derek and his equally dastardly father who targeted Lucinda at the same time he was moving in on Lily.

I still think of Alfred Molina as the “Throw me the idol and I’ll throw you the whip” guy from Raiders of the Lost Ark.

Same here. Unlike many other stars I saw in early roles and forgot, this one stuck with me, so that when I saw the TV ads for Dracula (the Broadway show), my first thought was “It’s Whatisname from The Twelve Chairs!”

I’ve seen him in too many things since to pigeonhole him as “Dracula” (although I re-watched the film a couple of nights ago, and his performance was excellent), including a performance of him as Salieri in Amadeus onstage. I’m sorry I missed his limited engagement several years back as Thomas More in A Man for All Seasons.

To me, he’s Skeletor.
