Not before 1974, when "Blazing Saddles" came out.
Harvey Korman played the character "Hedley Lamarr"--one of the running gags in the film was "Hedley" always being called "Hedy", to his consternation.
Of course!! I was being sarcastic like so many above, LOL.
I am old enough to remember seeing “Blazing Saddles” in theaters when it came out — wonder if it would be released today?? Most likely not. I had NO idea who Hedy Lamarr was until the WW II generation explained her to me
One of the favorite TV programs in our home, Dark Matters: Twisted but true, had a great episode on Hedy Lamarr.
