This is a great for a Back to the Future freak like me. Screenwriter and producer Bob Gale and Doc Brown himself, Christopher Lloyd. I know more useless and mundane details about the trilogy than anyone I know, and I still learned stuff from this video and thoroughly enjoyed it.
And also, can I say, something about the way the elderly present-day Lloyd reminds me of my maternal grandmother. Something about the way he talks and the pauses is just the way my grandmother spoke in her later years.
