Filmed in 1946-1947, but not released until 1952, The Cruise of the Zaca is acutally two cruises Flynn took at two different times (the color of the Zaca changes from white to black). It starts with Errol catching a helicopter to The Scripps Institute of Oceanography to meet with a group of scientists, and then agreeing to sponsor a research trip to collect rare fish and other sea animals. Along the way he picks up his father, a marine biologist, and his wife Nora Eddington, who by 1952 was in the middle of divorce proceedings from him.
There is some awesome footage of grey whales and other ocean activity, and great shots of the Zaca. Most of the rest of this short film, poorly narrated by Flynn himself, is pretty forgettable.
