My favorite film about fishing is one called "The Manzanar Fishing Club" It's available from the King County Library system on a DVD. Not sure about any streaming service. It's about guys who were imprisoned in camps during WW2, due to Japanese ancestry. They used to sneak out of the camps, under the wire, and hike up into the mountains, just to go fishing. Very inspirational. Plus interesting old fishing gear, some of it hand made.
