John Forsythe
Oh, Charlie. John Forsythe was the actor who played Charlie for the duration of the series. Although as mentioned prior, he was not the original Charlie. He never appeared on screen, and even when you did see the character it was usually only the back of his head but even then it wasn’t John but a body double.
Producer Aaron Spelling enjoys the mystery it created, not knowing what Charlie looked like. John Forsythe also notably starred in the iconic show Dynasty, where he played the role of Blake Carrington. Arguably, this was his biggest role in life. After Charlie’s Angels and Dynasty ended he continued to act until his death in 2010.
