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.
