An interesting find I came across today:

An Evening with Orson Welles is a series of six short films created in 1970 by Orson Welles, for the exclusive use of Sears, Roebuck & Co. Welles produced the recitations of popular stories for Sears's Avco Cartrivision machines, a pioneering home video system.[1]: 166  Five of the films are regarded as lost; footage from one, The Golden Honeymoon, is known to exist.

The reason it interests me is because one of the six short films was devoted to writings by G.K. Chesterton:

It even has an IMDB page:

Now if only it wasn't lost....
