At the start of the 1950s a Congolese cine-club was established in Léopoldville, and under Belgian instruction Mongita helped to shoot "La Leçon de Cinéma" (The Film Lesson) in 1951. Most of the club's Congolese members did not make films after independence, suggesting that their training had not been thorough, though Mongito did make one documentary in 1963.
