A native of Leipzig, East Germany, Schonherr started out as gravedigger before he found his way to the other side of the Wall in 1983. He got involved in setting up American underground film shows. Expanded his interests to Asia and toured American underground shorts through Japan in 1997, then took a program of Japanese cyberpunk movies on a tour through Europe in 1998. Went to North Korea to explore their films in 1999, screening bizarre North Korean propaganda epics at festivals and theaters in Europe in 2000.
He wrote about his strange movie exhibition travels in his book Trashfilm Roadshows (Headpress, 2002), recorded the development of North Korean cinema in his book North Korean Cinema – A History (McFarland, 2012).
Since 2003, he has been living in Japan as freelance writer on travel, film and food for Kansai Time Out, Midnighteye, Japan Visitor and others.
