Won’t You Be My Neighbor?, the documentary about Fred Rogers, is out tomorrow in select cities.1 Tim Grierson interviewed director Morgan Neville about the film for MEL magazine and Neville revealed this incredible story about how Rogers used to go back and edit some of his shows so they’d play better for children as times changed.

There’s one detail that I really liked that’s not in the film, which is he felt like the shows should be evergreen. As he often said, the outside world of the child changes, but the inside of the child never changes. So he thought his shows should play the same to two-year-olds now or 20 years ago. But as the years would go on, he would find things that had happened in old episodes that didn’t feel current, where maybe he used a pronoun “he” instead of “they” — or he met a woman and presumed that she was a housewife. So he would put on the same clothes and go back and shoot inserts and fix old episodes so that they felt as current as possible, so that he could stand by them 100 percent. I’ve never heard of that happening — it’s kind of amazing.

Amazing. As someone who regularly goes back into my archive to append updates to old entries, I love this anecdote so much.
