Back in 2018, I had a conversation with Dr. Robert Hieronimus  and Laura Cortner, authors of Inside the Yellow Submarine: The Making of the Beatles' Animated Classic - the definitive history of the 1968 film. But they are back with a sequel, delving deeper into the story: profiling others who made the vision a reality as well as exploring the greater context of the times and the deeper meanings to be gleaned from the film in It's All In The Mind: Inside The Beatles' Yellow Submarine. This newly-published follow-up is richly illustrated in full color and presents new stories from the creative minds who made the project a reality, despite considerable odds. It also illustrates how what shouldn't have worked did, and what meanings can be found, drawing upon classic myth.
