I Will Speak English (1954)

'An instructional film made on behalf of the Department of Social Welfare, demonstrating a new technique to teach English to illiterate adult audiences in the Gold Coast. (..) This is a film with an almost entirely African cast, depicting an African teacher instructing a group of African students, produced by a predominantly African crew. Yet, the subject of the film – encouraging the widespread teaching of English – jars with this image of a modern Gold Coast. Just as the Gold Coast Film Unit was overseen by British figures – such as Sean Graham and, in this case, George Noble – this film also endorses the retention of British influence within a new national identity'. - Tom Rice, for colonialfilm.org
