I used to find it funny how some would excitedly announce that some celebrity was supposedly a witness, as if that gave their own beliefs more confirmation and credibility
When people used to go on and on about Prince being a Witness, I'd want to say "Well you'd never know it!", or " Really?, Did you read his life story in the Watchtower?"....and when he , sadly, died, people actually said "This could bring a lot of people into the Truth!
Of course, Michael Jackson actually was mentioned in the Watchtower, about his " regrets" over supernatural images in his 'Thriller' video...and given the rest of his sad life, it's understandable that the 'organizatiion' has shied away from mentioning major celebrities in recent times
The one celebrity they once highliighted who really seemed to "walk the walk" was Theresa Graves, maybe not well remembered today, but a major (American) tv star in the 1970s. Among other things she was the first Black actress to star in a police detective series, 'Get Christie Love'.
Somewhere on youtube I heard a recording of the "testimony" she gave at a Witness Convention. It was a far cry from the scripted, ultra rehearsed presentations done today. She was very spontaneous and genuine. (and today they would Never let anyone go on at that length unscripted)
She told how she began studying while still pursuing her career. She recalled witnessing to actor David Niven on the set of a vampire movie, and related how when she began her tv series, the original producer agreed to respect her new beliefs. At her wish the stories could not be overly violent, nor have her character in immoral situatiions, or involve spiritism.
A later producer was not so accomodating, and after the show was over she left acting and, I believe, "pioneered" for the rest of her life. She tragically died in a fire.
