|Percy Helton (as Uncle Fester) Sneaks Up on John Astin (as Gomez)|
Recently, Life Magazine presented an article showing various actors and actresses trying out for roles in The Addams Family in 1964. Many people who care about such things have been trying to identify these performers. I collated all the info I could find on this matter and sent an e-mail to Mark Evanier, and he posted the bulk of it on his blog, News From ME.
Thankfully, he caught my mistake (D'oh!) of naming Percy Helton as a possible candidate for the role of Lurch. That would certainly be a non-starter, although, as you can see from the photo above, he just might have cut the muster as dear old Uncle Fester.
