The Secret Life of Walter Mitty
Three-Act Plot Analysis
"Walter Mitty" does not fit the three-act plot breakdown. Act I ends when the hero is fully committed to his journey, yet Walter Mitty never fully commits to any journey. You could argue that his "journey" is his imaginings, but the story begins and ends with a man already committed to fantasy instead of reality. There is no discernible "journey" to be found here, as this is not a grail-quest-type story.
