I could be wrong, but I don't think we've seen this? It's a great, hour-long "Masterclass" with Charlie at the 2009 Vancouver International Film Festival, moderated by Helen du Toit. (They call it a masterclass. It's an interview.) It's a fun watch, beginning with Charlie's anecdote about going for a walk around Vancouver. Other stuff covered: Adaptation, Malkovich, Eternal Sunshine, Elijah the chimp, Charlie's brief foray into standup, women, Ellen in Synecdoche... Lots of good stuff! Obviously Antkind and Ending Things are not covered, since those came years later.
It popped up in my alerts a couple of weeks ago. I suspect the video was private before then.
