Hitler in Colour, a 2005 documentary film narrated by Scottish actor Brian Denis Cox (X-men 2) which comprises almost all known colour footage of Adolf Hilter in the rise of the Nazi party and during World War 2.
The result is a documentary which provides a 12-year account of Germany under Nazi rule from 1933 to the fall of Berlin in 1945, all in full-colour film. As well as showing this tumultuous political period in history with Hilter at the helm, the documentary also provides a full-colour account featuring some aspects of the Fuhrer's personal life which were exclusively shot by his girlfriend Eva Brun.
Those personal clips were all recorded at Hilters get-away-retreat; The Berghoff in Bavaria, Austria. Even then he only allowed Eva to film a refined version of him as the Fuhrer.
