In the 2005 remake of Bewitched, starring Will Farrell and Nicole Kidman, I heard Farrell’s character Jack Wyatt make a joke about the actor who played Darrin being switched out without being noticed. I was never a huge fan of Bewitched but I was sure I would have noticed them pulling a fast one.
So I looked into it and Darrin was indeed replaced in 1969. First played by Dick York then Dick Sargent after York had and unfortunate accident and could not continue. In all Bewitched ran from 1964 to 1972 and I didn’t notice the swap; it is my secret shame.
But to be fair Sergent does look like a fetal York ripped out of his mother and matured slowly in a jar.
but you make up your own mind about that.
