Edgar Buchanan, AKA Uncle Joe from Petticoat Junction as a good bad guy in Have Gun Will Travel.
Also Morgan Woodward from the Big Valley, but that isn’t surprising, he was all over the damn place.
Steve McQueen on Track Down, a western featuring Robert Culp later of I Spy.
McQueen played a bounty hunter named Josh Randall, and the network gave him his own series, Wanted Dead or Alive.
Collin Wilcox, aka “Mayella Violet Ewell” in To Kill a Mockingbird, was a hot teenager in “Number 12 Looks Just Like You” on Friday’s Twilight Zone.
She was also the hot widow who threw a glass of wine in Robert Conrad’s face in an episode of Columbo.
I just watched an episode of Alfred Hitchcock Presents with a very young Roger Moore as a police inspector.
I just found out that “Carrie,” the daughter of the Unemployment Office official in “The Boyfriend, Part 2” on Seinfeld (i.e., the girl George dates), was the late Carol Ann Susi, aka “Mrs Wollowitz” on The Big Bang Theory! :eek:
Robert Conrad spent an entire series as a Honolulu detective on the series Hawaiian Eye.
In fact, since 77 Sunset Strip and Hawaiian Eye were made by the same people, this was probably a “crossover” , or at least a trial.
Cool. Fans of one show are introduced to another. $$$ 
There was an episode of this on YouTube (at least a partial one) featuring Barbara Bain of Mission: Impossible fame. IIRC, she played a truly desperate housewife who went along with an armored car heist to keep her husband out of jail.
I don’t know if the missing segment was ever added, but I’d really like to see more of this show. I vaguely remember it (along with Surfside Six) from when I was in Kindergarden or First Grade.
77 Sunset Strip I definitely remember from my preschool days.
Robert Conrad was my favorite actor in the early '70s (I was late to Wild Wild West, but scarfed it down), and I watched like a stalker for any sign of him in anything (“The DA,” “Assignment: Vienna,” “Five Desperate Women [TVM]”*). Years later, I suffered through, “Jingle All The Way,” and didn’t realize until the credits that the cop was RC (didn’t he get blowed up real good–cartoon style?).
*“FDW” was the first thing I saw where RC dies at the end–he’s the bad guy. I was sniffling for his death, which was hardly the point of the movie.
George “Goober” Lindsey, Michael “Principal Kaufman” Constantine, Paul “Dr Piper” Fix, and Ivan “Sgt Kinchloe” Dixon in “I Am the Night–Color Me Black,” a real “message” episode of Twilight Zone.
George “Mr Sulu” Takei in “Encounter” on Twilight Zone.
A couple of Doctor Who actors far from a TARDIS
Patrick Troughton (Classic Doctor 2) played Phineus in Jason and the Argonauts, almost unrecognizable with a heavy beard.
Peter Davsion (Classic Doctor 5) showed up on All Creatures Great and Small His goat was sick or something like that.
Peter Capaldi was in World War Z just before being cast in his best-known role. He played a physician with the World Health Organization billed as (appropriately enough) “WHO Doctor.”
Davison didn’t just “show up” on All Creatures. He was a regular cast member, playing young veterinarian Tristan Farnon. Indeed, All Creatures is what brought him to fame, and pre-dated his time on Doctor Who by a couple of years.
I hate it when that happens!

Star Trek’s Mr. Atoz in a 77 Sunset Strip Episode, Dial S for Spencer.
Tim Russ was in Star Trek ng episode
He actually appeared in three different incarnations of ST before being cast as Tuvok on VGR:
Yes!!
Mr. Atoz (the character, not me) was Ian Wolfe. He had a very long career, starting in the 1930s and lasting until 1990. He was one of those guys who was in everything. Wikipedia claims “around 400” roles in film and television. And that’s not even counting his theater work, which was also extensive.
He always looked like a little old man, even in his thirties!
