The East Anglian Film Archive have a massive collection of films shot in the region dating back to the beginning of the 20th Century. These include films made by different companies, home movies and TV material. They are always pleased to arrange screenings for local groups and can often put together a programme specific to your area or on a particular theme.
The EAFA do not hire out their films like Filmbank or the BFI, but they will put together a programme and provide a speaker to introduce it. To cover expenses they charge a fee starting at around £55 (inc VAT).
