Frank Gorshin, RIP
I'm not certain, but I think Frank Gorshin introduced me to idea of actors as real people. My little 4 or 5-year-old brain vividly seized upon the fact that the guy who was the Riddler on the 60s Batman TV series seemed to be the same guy in the wild black-white face make-up in that Star Trek show—and boy was Bele sweaty!
Gorshin carved out a successful decades-long career based on his sheer energy and a knack for doing impressions. That and he stayed married for 48 years. Sounds like a good life all around.
