The film was produced in Spain and on an estimated budget of $24,000, according to Roger Ebert.
To conserve money, Nava and Thomas used costumes and props remaining from Samuel Bronston's El Cid.
Film locations included the castles of ancient Segovia, Spain.
The film opened in a limited theatrical release in New York on November 17, 1977.
The New York Times film critic Vincent Canby wrote: "The Confessions of Amans was a very beautiful film, though not an especially pretty one, a chilly, tightly disciplined tale of the tragic love affair of a young philosophy tutor and the wife of the lord of the manor.
