John Doo

Chien Lien Tu, best known by his stage name John Doo, was a Chinese-Brazilian filmmaker, director of photography screenwriter, producer, and occasional actor.

Doo was part of a recurring team of filmmakers, actors and producers in São Paulo's "Boca do Lixo", a downtown square that became a pole of production and distribution of erotic and pornographic films. Among the highlights of his career are partnerships with David Cardoso and Ody Fraga, the three of them collaborating in a series of anthology erotic films.

Born in Chongqing, China in 1942, Doo moved with his family to Brazil, at age 8, and in 1963 got his first professional gig in Brazilian cinema, working as continuity supervisor in Amacio Mazzaropi's "O Cabeleira". He would go on to be assistant director in Mazzaropi's "O Puritano da Rua Augusta" (1965).
