Mankurt (Russian: Манкурт; Turkish: Gün Uzar Yüzyıl Olur)[1] is a 1990 Soviet film written by Mariya Urmadova[2] and directed by Hojaguly Narliyev.

[3] The main cast were the Turkish actors Tarık Tarcan [tr] and Yılmaz Duru [tr] and the Turkmen actors Maya-Gozel Aymedova and Hojadurdy Narliyev.

[10] The film is based on the fictional legend about a mankurt within the novel The Day Lasts More Than a Hundred Years ("И дольше века длится день") by Chinghiz Aitmatov,[11] a philosophical tale about what can happen to people if they forget their motherland, language, and history.

[3] The Turkic legend invented by Aitmatov for the novel conceives of a cruel way of making mankurts of captives in the hopes that they will forget everything but basic activities, rendering them servile minions to Zunghar conquerors.

He is so completely turned that he does not recognize his mother and kills her when she attempts to return his memories.
