I know I shouldn’t just flag up random Youtube videos, but there is a moment in this at just after the 4:15 mark which is simply awesome. Zark knows how he managed it, but somme random American guy got the cast of Back To The Future together for a Zoom meeting, and the result is frankly incredible. They clearly get along, exchanging banter and stories. They even re-perform some of the script at one point. The result is nostalgic and funny, and frankly has made my day.
