Powers That Be (documentary)

I was watching All in the Family and they were talking about a special on the environment with Jack. It was called Powers That Be and it was produced by Don Widener of KNBC, who did a lot of documentaries about environmental problems and nuclear power. Widener had met the pediatrician who cared for Jack's children, and the pediatrician had given him a earful about what pollution was doing to kids' lungs. He later wrote an authorized biography of Jack.

Now I want to add not just the documentary but Don Widener's name to the IMDB, I checked the help screens, but I can't find a way to add a person. Someone point me in the right direction?

Well, the city's being built and I'm winning this game. So don't interrupt us with trifles.
