Major ‘Documentary Centenaries' season at BFI Southbank Restored ‘Night Mail' DVD, released by BFI. ‘Land of Promise' DVD box-set containing 41 of the restored titles, due April 2008.

Film season was largest-ever Documentary Movement retrospective. Many titles newly accessible, others at much-improved quality. See ‘ Eastern Valley': bad 16mm print was only available British material; outstanding new 35mm version produced from original nitrate print obtained from USA. ‘Night Mail': a classic available looking its best in decades. ‘ Land of Promise' box-set will make wider selection of restorations available worldwide: see selection. Preservation material produced: this holistic project married public access to long-term legacy.
