Recovering lost works of British silent cinema is "incredibly rare", the British Film Institute has said.
Bryony Dixon's comments to the Today programme come as the 1923 film Love, Life and Laughter - starring Britain's most successful silent actress Betty Balfour - was recovered in the Netherlands.
Ms Dixon said the vast majority of films from the era were recycled for their silver content.
First broadcast on BBC Radio 4's Today programme on Thursday 3 April.
