How the magnificent Mitchell & Kenyon collection was resurrected, thanks to the dedication and skill of the BFI National Archive.

In 1994, hundreds of rolls of film, shot in the earliest years of the 20th century by filmmaking partnership Mitchell and Kenyon, were discovered in a Blackburn basement. This revealing documentary takes you inside the BFI National Archive, throwing light on the epic endeavour to restore this magical footage and return to us an astonishing record of our late-Victorian and Edwardian ancestors.
