Tommy Kirk’s passing earlier this week eliminated or greatly winnowed the surviving casts of many old Disney movies from the 50s and early 60s. Among his many credits, I believe he was the last surviving principle cast member at least of Swiss Family Robinson, The Absent Minded Professor, and Son of Flubber. His death also appears to leave only one surviving principle cast member from Old Yeller, The Shaggy Dog, Babes in Toyland, The Misadventures of Merlin Jones and Bon Voyage!
I’m sure there are many more that could be added to the list, he had a prolific career as a child and teenager. However, his career with Disney came to an abrupt end in the mid-60s when studio executives discovered that he was gay. RIP.
