A huge undertaking for Spanish cinema in its day, it was the longest film version of the novel up to that time (two hours and twelve minutes, plus an intermission), and very likely the most faithful, reverently following the book in its dialogue and order of episodes, unlike G.W.

The music for the film was composed by Ernesto Halffter, and the movie was shot on location in La Mancha and other Spanish regions.

Alonso decides to take the name of Don Quixote de la Mancha for his exploits, however along the way he wanders several times, mistaking mills for giants and flocks of sheep for armies about to engage in a fight.

After freeing some prisoners almost by accident, he decides to stay exiled in the mountains to pay for his actions, but then between Sancho Panza, the priest and the barber, they manage to bring him back home in a wooden cell.

His misadventures will be collected in a book that will soon spread throughout Spain, because of that many will already know his name, but not because of his fame, but because of the madness that lives in the mind of Don Quixote de la Mancha who believes he is a gentleman walking in an age where they no longer exist.
