Probably wasn't the very first, but it was certainly one of the earliest I remember.

Weirdly, I don't have a really strong memory of it. But I do remember going to visit the Chaplins' house in Switzerland as a little kid, and having the lovely Una Chaplin project prints for us... some Charlie Chaplin films, a few other movies.

I've just remembered - I think I may have seen Kubrick's Barry Lyndon there!
