They Shall Not Grow Old is a documentary produced by New Zealand-based Sir Peter Jackson, of The Lord of the Rings trilogy, and his high-tech studio Wing Nut Films, in collaboration with the Imperial War Museum.
The film footage used is entirely authentic to the war, but the speed has been re-regulated and the images digitally cleaned, improved and colorized, with stunning results. The soundtrack is taken from interviews with British veterans that were recorded forty or fifty years ago. The run time is 99 minutes and the theater version is available in 3-D.
Yesterday there was a one-night showing at theaters in the U.K. which fulfilled the objective of qualifying the piece for film awards, and due to the high popularity the run has been extended.
BBC One will broadcast the non-3D version in HD on November 11th. There is no word yet on when it might be shown in the U.S., either in theaters or on public television.
