I swear these guys look/looked the same throughout their entire professional lives (as in, they sprang from the womb as fully-formed middle-aged men):
Norman Fell (Mr. Roper; recently saw him in a 1960s film with Ian McKeller and Suzanne Pleshette – looked exactly the same)
Ed Asner
Lionel Stander (Hart to Hart; saw him in an old TCM flick – though he had darker hair he looked/sounded the same)
Abe Vigoda
Burgess Meredith
Kevin Spacey
John Lithgow
Steve Martin
I suppose it depends a bit on what you think “middle-aged” looks like. In the roles I’ve seen them, none of those would have looked out-of-place playing characters in their mid-30s and above. Even Martin in The Jerk looked older than his character was supposed to be.

My point of reference is ca. 1977 (when I was 10) to the present.
