The Future of StoryTelling (FoST) has released several new videos about speakers at its annual summit, taking place October 5-6 in New York City. One of those speakers, above, is about film production designer Alex McDowell, who talks about “world building” — and how stories spring from a fully-imagined world.

FoST brings together leaders from the worlds of media, technology, and communications to explore how stories are changing in the digital age.
