Joe Berlinger (born October 30, 1961) and Bruce Sinofsky (March 31, 1956 – February 21, 2015) were a team of American documentary filmmakers that have won cult fame and critical acclaim. The duo are probably best known for their trilogy of Paradise Lost films about the so-called West Memphis Three, and for their 2004 Metallica documentary Metallica: Some Kind of Monster. Though they often worked together, Berlinger and Sinofsky also separately directed their own projects.
