Unlocking Film Heritage (UFH) was one of the biggest film digitisation projects ever undertaken and it encompassed the BFI National Archive together with national and regional audiovisual archival institutions in United Kingdom. Between 2013–2017 around 10,000 titles, capturing 120 years of Great Britain on film, were digitised and made free-to-access in a variety of ways. Many archival clips can be watched for free online via BFI Player.
