João César Monteiro was born into a family with anti-clerical and anti-fascist ideals. His family moved to Lisbon when Monteiro was 15 years old to enable him to continue his studies. In 1963, with a grant from the Calouste Gulbenkian Foundation, Monteiro traveled to Great Britain to study at the London Film School (known then as the London School of Film Technique). In 1965 in Portugal, he began work on his first film, Quem Espera por Sapatos de Defunto Morre Descalço (Who Waits for the Deceased’s Shoes Dies Barefoot), which would not be finished for five years due to financial problems. At the same time, he made the short documentary “Sophia de Mello Breyner Andresen”, about the Portuguese poet. Monteiro also wrote film criticism for periodicals like Imagem, Diário de Lisboa and O Século.

His first feature film was Fragmentos de um Filme Esmola: A Sagrada Família (1972). In 1982 he made Silvestre an adaptation of traditional Portuguese folk stories. Silvestre was shown at the Venice Film Festival and was an important step in his international recognition. À Flor do Mar (1986), featuring Laura Morante, was shown at the Salsomaggiore Film Festival, where it won the Special Jury Prize. Monteiro returned to the Venice Film Festival in 1989 with Recordações da Casa Amarela (Silver Lion), a film that marked the introduction of the character João de Deus. In 1992 he made O Último Mergulho – esboço de filme, featuring Fabienne Babbe.
