Scriptnotes in general is a good one for anyone wanting to get a better understanding of movies, television, and storytelling. Bonus points because John August builds modern tools for screenwriters including apps for reading and writing screenplays (Weekend Read & Highland), a new markup and file format (https://fountain.io), and they even designed a new version of the Courier font (Courier Prime). Lots of interesting crossover between the world of making movies and the world of software development and startups.
