If you search the name “Ellis Haizlip” in your preferred search engine of choice today, you won’t get a lot of results. There is no Wikipedia page, and his IMDB spotlight is slim, to say the least. Most of what you’ll get are stories and reviews about Mr. Soul, the documentary detailing the life and career of Haizlip and his time as the producer and host of “Soul!” from 1968 to 1973. A documentary, I might add, that most people wouldn’t even know to search the name of because much like the person it’s analyzing, it wasn’t massively advertised. Still, Mr. Soul is just as important to American life and TV as the man himself was.
