Wil “Wesley Crusher” Wheaton and Julie “Soron” Culea in the St Elsewhere episode “Nothing Up My Sleeve.”
Jeffrey “Capt Pike” Hunter, Majel “Nurse Chapel” Barrett, and Angelique “Shahna” Pettyjohn in A Guide for the Married Man (1967).
Brent “Data” Spiner as “film director Larry Stein” in the Hill Street Blues episode “The Life and Time of Dominic Florio, Jr.”
Patti “Nurse Temple” Tippo as “porn star Lulu” in the same ***HSB ***episode.
Morgan Woodward, Dr. Simon van Gelder in Dagger of the Mind and Ron Tracey in the Omega Glory, in The Jed Polke Story of Wagon Train. The guy was in seven wagon train episodes.
I haven’t read the entire thread so this may have already been mentioned. The Cheers episode “Never Love a Goalie: Part 2” has Brent Spiner and John Fleck (he played Silik on Enterprise).
Gerrit Graham (“The Hunter” in DS9 and “Quinn” in VOY) as “Mr Gilette” in the St Elsewhere episode “Cold War.”
Jon Lormer (“Tamar” et al.) as paleontologist “Professor Dactyl” in the ***Batman ***episode “How to Hatch a Dinosaur.” Yet another crossover guest star.
Bruce Mars (“Finnegan” et al.) as *Seaview *guard “Hawkins” in the Voyage to the Bottom of the Sea episode “The Abominable Snowman.”
Joseph Ruskin and Gene Dynarski (“Galt” and “Ben”/“Krodak”) in the*** Hill Street Blues ***episode “You’re in Alice’s.”
I just saw James Doohan as “Mr Bonner” in a movie from the National Film Board of Canada that I’d date to around 1957. Unfortunately, I missed the first few minutes on *Silver *Screen, so I’m not sure of the title, but I suspect it was The Ticket, in reference to a young convict who was out on parole.
I just today realized that Bruce “Dr Seth Griffin” Greenwood in ***St Elsewhere *** was “Capt Christopher Pike” in 2009’s Star Trek.
Leonard Nimoy in the Wagon Train episode, The Tiburcio Mendez Story, playing a Mexican bandit. He had a rough time until Star Trek.
“I weel keel him! Who is he?” is not logical or good acting.
Huh. I watched HSB regularly and didn’t make that connection at all. Thanks!
It’s the episode where JD’s “Home Security” video was transformed into a porn flick without his knowledge.
Gotcha. And here’s a scene from it: HSB-1 - YouTube
Harvey Jason (“Felix Leech” in TNG’s “The Big Goodbye”) as “Scudder” in the “Londinium” episodes of Batman.
Peter Mark Richmond (TNG’s “Ralph Offenhouse”) in the Voyage to the Bottom of the Sea episode “Secret of the Deep.”
