I was excited to find this database http://www.colonialfilm.org.uk/home
The files on our motherland include documentaries and short films from as far back as 1933.
Some educative, some entertaining and some just hard to take.
Mouse-over "Search Film By Country", and go from there.
Some of the films you will find are:
I Will Speak English
The Boy Kumasenu
Mr Mensah Builds a House
Progress In Kojokrom
