I think my first “celebrity” (if you could have called her that back then) crush was Mellisa Joan Hart when she was on “Clarissa Explains it All” on Nickelodeon.
I was probably 10 or 11, and according to IMDB, she was 15 or 16 at the time.
She’s still looking pretty good, which makes sense since she’s only in her mid-30’s.
Would have either been James Mason or Christopher Lee. Both stayed remarkably attractive - Lee still, and Mason right up to his death. It’s the voices and the dark, slightly cruel eyes.
