John-Boy Walton – The Waltons

Considering that the show The Waltons is seen from the point of view of John-Boy, it’s a pretty bold move to replace the actor who played him with somebody else. That didn’t stop the creators of the series from doing exactly that.

Richard Thomas initially portrayed the character through more than half of the series’ run. Robert Wightman subbed in thereafter as John-Boy, who was the eldest of seven children in the iconic TV family.
