In the 1990s, Valeriu Gagiu's work focused on the genre of documentary film. During the Romanian Revolution of 1989, Valeriu Gagiu is one of the few Moldovan filmmakers to have captured the dramatic pages of the events of that time, making the documentary feature film "Bloody Christmas" (1989). In 1992, he was next to the first line Moldavian combatants and volunteers during the armed conflict on the Dniester river, and wrote the play "The Duet for two snipers" reflecting some images of this war (a fragment was published in "The Magic Lantern" 2-3 / 1996).
