Film as a medium first arrived to Nigeria in the late 19th century, in the form of peephole viewing of motion picture devices. These were soon replaced in early 20th century with improved motion picture exhibition devices, with the first set of films screened at the Glover Memorial Hall in Lagos from 12 to 22 August 1903. 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. As of 1954, mobile cinema vans played to at least 3.5 million people in Nigeria, and films being produced by the Nigerian Film Unit were screened for free at the 44 available cinemas. The first film entirely copyrighted to the Nigerian Film unit is "Fincho" (1957) by Sam Zebba; which is also the first Nigerian film to be shot in colour.
