The Defender is a 54-minute Canadian documentary film, made in 1988 by the National Film Board of Canada (NFB) and directed by Stephen Low. The film depicts the building of the Diemert Defender, an emergency fighter aircraft project by Bob Diemert, an eccentric Canadian aviation engineer. His dream of building the next Canadian strike fighter aircraft to challenge the might of the Soviet Union in the event of invasion was dependent on selling a restored warbird.
