GREAT SCOTT! This is heavy.
There’s a podcast that started in late 2015 that, like the “Star Wars Minute”, tackled the “Back to the Future” trilogy, dissecting every minute of the movies in 15- to 20-minute segments.
The podcast link at the iTunes Music store only covers the last 300 episodes, so the first 50 podcasts (for the first 50 minutes of the first movie) have to be listened to or retrieved from the website.
That should cover about the next two years of road trips.
