About the film
Topaz is a 1945 documentary film, shot illegally by internee Dave Tatsuno (1913–2006),, which documented life at the Topaz War Relocation Center in Utah during World War II. Tatsuno went through a unique and challenging filming process in order to produce his movie due to lack of freedom within the internment camps that hindered his ability to film his experiences.
