As both of the movie and story are different with extra parts, missing parts, and other elements of course, both seem to partially make one of the themes stand out. In the short story and movie, The Secret Life of Walter Mitty, written by James Thurber, the protagonist Walter Mitty is a daydreamer who goes through a day of ordinary tasks and errands, and he escapes into a series of romantic fantasies, each spurred on by some mundane reality. This phenomenon is common in people’s daily life shown by a large-scale study in which participants spend forty seven percent of their waking time on average on daydreaming.

Daydreaming is the stream of consciousness that detaches from current external tasks when attention drifts to a more personal and internal direction.

Everyday a regular person finds themself daydreaming, pulling their imagination out to escape the real world to pass time.
