Colonial filmmakers started producing films for local audiences within Nigeria since the 1920s, mostly employing the mobile cinema as a means of exhibition; the earliest feature film made in Nigeria is 1926's "Palaver" produced by Geoffrey Barkas. The film was also the first film ever to feature Nigerian actors in a speaking role. Nigerian film actors featured in "Palaver" include Dawiya and Yilkuba. The film was shot amongst the Sura and Angas people of the present day Bauchi and Plateau States in Northern Nigeria, and narrates the rivalry between a British District Officer and a tin miner which leads to a war. Also in this era there were several films set in Nigeria, one of the most notable being 1935's "Sanders of the River" by Zoltán Korda, featuring Nigerian actor Orlando Martins. Martins also featured in other notable films including "The Man from Morocco" (1945), "Men of Two Worlds" (1946) and so on, and this established Martins as one of the recognized Nigerian actors of his time.As of 1921, there were four other halls showing films twice a week in Lagos Mainland and one hall each in Ebute Metta and Oshodi. By this time, cinema had become popular in Lagos with crowds of young and old people usually waiting at the doors of theatre halls. Religion also aided in the expansion of cinema culture as the Christian missionaries used cinemas for religious propaganda.
