History IWantYouToMeetAnOldFriendOfMine / LiveActionTV

** Creator/ChristopherLloyd, who co-starred with Creator/JuddHirsch on ''Series/{{Taxi}}, guest-starred in season four episode "Graphic" as a famed comic book writer.

** Tom Wopat appeared as an old friend of John Schneider's Jonathan Kent character. Both actors starred on ''Series/TheDukesOfHazzard''. They even had some {{Mythology Gag}}s: They had them riding around in Wopat's character's car, which looked suspiciously like the ''General Lee'', and even repeated the old ''Dukes of Hazzard'' gag of the passenger side door not working and having to climb in through the window. Lex referred to Wopat as Jonathan's "Good Ole Boy", a reference to the ''Dukes'' theme song. They even mentioned several {{Noodle Incident}}s involving Jonathan and Wopat's character outrunning the local sheriff when they were young!

* In an episode of ''Series/{{Coach}}'', Luther (played by Jerry van Dyke) learns that he was adopted and ends up attending a reunion of his birth family. As he enters he complains to Hayden that there's no way he could be related to any of these people. An unnamed character (played by Creator/DickVanDyke) chooses that moment to walk conspicuously across the set.

* ''Series/InPlainSight'' stars Mary [=McCormack=], who played Kate Harper on ''Series/TheWestWing''. In the second season, her character's sister dates a character played by Joshua Malina. Malina's and [=McCormack's=] characters dated on TWW, and there is an odd look when their characters meet. Also, in the same episode, fellow ''Series/TheWestWing'' alum Richard Schiff guest stars (as [[ImplacableMan The Implacable]] [[NinjaPirateRobotZombie Rabbi Detective]]), and he and [=McCormack=] share a classic [[WalkAndTalk Sorkin Pedeconference]] through the halls of a hospital at the end of the episode.

** Also, Creator/RichardDeanAnderson knew Creator/ChristopherJudge and Creator/DonSDavis from ''Series/{{MacGyver}}''.

* ''Series/{{CSI NY}}'' had two. One of Creator/GarySinise's costars from the miniseries of ''Series/TheStand'' appeared in the season one episode "'Night Mother," though they had only one brief scene together. More prominently was Mac's boss Sinclair played by Creator/MykeltiWilliamson, who starred alongside Gary as Bubba in ''Film/ForrestGump''.

* Creator/ScottBakula also was imprisoned by his ''Series/QuantumLeap'' sidekick Creator/DeanStockwell in ''Series/StarTrekEnterprise''.

* Averted in ''Series/DoctorWho'', in Creator/PeterCapaldi's first season as the Doctor, his ''Series/TheThickOfIt'' co-star Chris Addison had a recurring role as Missy's henchman. The two had no prior onscreen relationship, and never even met face to face.

* ''Series/KungFu''
** The show featured an old preacher named Serenity Johnson in a few episodes. He was played by Creator/JohnCarradine, father of show star, David Carradine.
** The first episode with him also featured a teenage Robert Carradine (David's brother/John's son) as Serenity's mute sidekick, Sunny Jim.

* Adrian Edmondson could have been cast in the ''Series/{{Blackadder}} Goes Forth'' episode "[[Recap/BlackadderS4E4PrivatePlane Private Plane]]" for the sole reason of appearing against Creator/RikMayall, his long-time work partner. In their double-act, most of the constant violence (and occasional gay jokes) are directed at Mayall, so it seems too much of a coincidence that [[spoiler:Mayall's Flashheart immediately shoots Edmondon's Red Baron]] and loudly proclaims "What a '''poof!'''"

** Creator/PeterCapaldi's ''Series/TheThickOfIt'' costar Creator/ChrisAddison had a recurring role as Seb in season eight. Sadly, they didn't share any screentime.

* George Cole was reunited with his ''Series/{{Minder}}'' costar Denis Waterman when he made a guest appearance on ''Series/NewTricks''. Sadly, John Thaw died before the series was made, thus denying us the chance of seein [[Series/TheSweeney Regan and Carter]] reunited.

** One episode of ''Series/{{CSI}}'' had Creator/LeaThompson and Creator/ElisabethShue opposite one another. They'd previously started out in a series of Burger King advertisements in the early 80s, and also appeared together in ''Film/BackToTheFuturePartII'' and ''[[Film/BackToTheFuturePartIII Part III]]'', respectively appearing as Marty [=McFly=]'s mother Lorraine and girlfriend Jennifer ([[TheOtherDarrin with Elisabeth replacing Claudia Wells]]).

* ''Series/{{CSI NY}}'' had two. One of Creator/GarySinise's costars from the miniseries of ''Series/TheStand'' appeared in the season one episode "'Night Mother," though they had only one brief scene together. More prominently was Mac's boss Sinclair played by Mykelti Williams, who starred alongside Gary as Bubba in ''Film/ForrestGump''.

** Creator/JohnWesleyShipp, Amanda Pays, Creator/AlexDesert, Vito D'Ambrosio, Corinne Bohrer, and Creator/MarkHamill are a case of RemakeCameo. They were all cast members of [[Series/{{The Flash 1990}} the 90s Flash series]], with the latter two both having {{Role Reprisal}}s. Shipp, who played the titular hero in the [=90s=] series, plays [[CastingGag the titular hero's father in the current one.]]

* When Creator/BradPitt appeared on ''Series/{{Friends}}'', his character was an old acquaintance of Creator/JenniferAniston's . However, he hated her and she barely remembered him.

*** As well as Creator/JuliaRoberts, who dated Creator/MatthewPerry, and Creator/DavidArquette, who married Creator/CourteneyCox (though technically Arquette appeared well before he and Cox became involved, his character didn't even share a storyline with Cox's character Monica)..

* Gratuitous example: Creator/TeaLeoni (Mrs Duchovny) and Creator/GarryShandling appearing in ''Series/TheXFiles'' as themselves playing Mulder and Scully in a movie.

** The show featured a old preacher named Serenity Johnson in a few episodes. He was played by Creator/JohnCarradine, father of show star, David Carradine.

* Almost subverted in ''Series/BabylonFive''. When June Lockhart made a guest appearance, J. Michael Straczynski refused to write a scene in which her character meets Lennier, played by her ''Series/LostInSpace'' co-star Bill Mumy, as there was no logical reason for the two to meet except for such a joke. However, Mumy himself wanted to do an in-joke about it, and so without permission he snuck into one of her scenes out of his alien makeup as an extra and gave a quick smile to her.

* Adrian Edmondson could have been cast in the ''Series/{{Blackadder}} Goes Forth'' episode "[[Recap/BlackadderS4E4PrivatePlane Private Plane]]" for the sole reason of appearing against Creator/RikMayall, his long-time work partner. In their double-act most of the constant violence (and occasional gay jokes) are directed at Mayall, so it seems too much of a co-incidence that [[spoiler:Mayall's Flashheart immediately shoots Edmondon's Red Baron]] and loudly proclaims "What a '''poof!'''"

* ''Series/{{Angel}}'' co-stars Christian Kane (Lindsey [=McDonald=]) and Creator/SamAnderson (his evil boss Holland Manners) were reunited in an episode of ''Series/{{Leverage}}''. Kane (Eliot Spencer) was part of a con against Anderson's one-episode character, and says that they winked at each other on-screen to reference their history.

* In ''Series/TheWestWing'', Creator/MartinSheen offers William Devane the job of vice president. The last time they faced each other in the oval office was in the 1970's, in ''The Missiles of October'', when they played Robert and John F. Kennedy respectively. Both were doing Mayor Quimby accents back then, of course.

** In another episode, entitled "Family Ties", Creator/JasonBateman's character meets a woman he thinks is his long-lost sister, but turns out to be prostitute. She's played by his actual sister, Justine Bateman, who's most famous for her role on ''Series/FamilyTies''.
