Answer: Mr. Rogers
Horror director and producer George A. Romero, best known for his classic zombie films Night of the Living Dead, Dawn of the Dead, and Day of the Dead, as well as other films including The Crazies, Creepshow, and The Dark Half, was originally the director of more wholesome films.
In the early 1960s, Romero got his start doing short film work for the iconic children’s show Mister Rogers’ Neighborhood. Romero, like everyone else who had dealings with Fred Rogers, had nothing but glowing things to say about him. In a 2010 interview with the San Francisco Chronicle, Romero shared his memory of, and respect for Rogers:
He was a beautiful guy. He was the sweetest man I ever knew. What you see is what you get. That was Fred. In some ways he was still 10 years old. He was a wealthy guy, but very dedicated. He was a super wealthy cat — he could have just said “Forget about it.” But he was dedicated to educating kids and telling them “There’s nothing wrong with you. I like you just the way you are.”
Perhaps even more endearing, Rogers—in a show of support for Romero—attended screenings of his early horror films.
