Grant, I know this isn't what you meant, but I can't resist. Watching "Fade Into Murder" the other night, I saw an actor credited as Frank Emmett Baxter play a role exactly the way he played a role in "Lady in Waiting", where he was credited as Frank Baxter.
In both he played the "annoyed executive"---exact same demeanor and facial expressions, except in "Fade Into Murder", no one slapped him down like Beth Chadwick did.
The episodes were five years apart.
I don't recognize him from any of his other work, so I don't know if that was his specialty.
Ray Milland in "Dial M for Murder" and "Columbo: The Greenhouse Jungle". They also managed to cast John Williams in a Season 2 Columbo episode as well.
