At the end of 1996 in an old shop in Vienna specialising in film materials I found a tin with indeterminable pieces of 16mm film showing much wear and tear. They dated from the late 60s. After a cursory glance I thought 'yes'. The found footage material was ideal for the horror series. Corridor is the 5th film in the horror series "Black Garden‘ along with The Murder Mystery (1987/92), Blicklust (1992), Party (1995), Macumba (1995/96).
