Viktor Ivanovich Tregubovich was born on November, 30th 1935 in Sakhalin Village of the Krasnoyarsk Region. In 1953-1954 he studied at Prokopyevsk Mining College, and worked as an instructor of the district Komsomol (Young Communist League) committee. In 1963 he graduated from Film Director's Faculty of VGIK (where he had studied under M.I.Romm), and then became a director at Lenfilm Studio (St. Petersburg).

The first full-length feature film by Viktor Tregubovich was the rural drama Hot July (1965) dwelling on the “fathers and children” conflict and the changes occurring after dethronement of the personality cult. In his film At War as at War (1968) Tregubovich tells about everyday frontline life and feats of the "anonymous” soldiers of the Great Patriotic War. Having addressed the theme of civil war in Altai (Dauria (1971), the film director created a captivating and spectacular film-novel with an adventure plot and memorable characters (their roles played by Vitali Solomin, Yuri Solomin, Vasili Shukshin, Yefim Kopelyan and other stars).

In the film Old Walls (1974) Tregubovich found an interesting solution to the industrial theme, having put in the center a non-typical for the Soviet cinema image of the woman-director played by Lyudmila Gurchenko: her character, the director of a weaving factory, is breaking free from the out-of-date imperatives of her social role, which fettered her not only as a woman in love, but also as an innovatively thinking organizer of the manufacture.

In future Tregubovich repeatedly addressed the social and industrial problems (Wrong Connection (1977), The Highway (1983) and moral problems (When you are leaving - leave (1978), and Journey to Another Town (1979). In 1984 he found a new approach to these problems, having transformed them into the satirical comedy (A Rogue's Saga (1984)). An officer of a scientific research institute Lyubomudrov played by A.Kalyagin represented a version of Tchitchikov operating during the Soviet epoch of "stagnation" with its typical "deficiency", string-pulling and hypocrisy. In the beginning of Perestroyka (1987) Tregubovich paid tribute to "extreme" plots, having introduced "strange" characters and mystic tragic collisions in his psychological drama Tower (1987). The film, however, just like the followed by Drunkenness - First Film: Strength (1991) - "a national epopee from dissenting life" was lost in the stream of numerous "films without the spectator" that were released on the turn of the 1980s-1990s. Subsequently Tregubovich worked as a producer, and played an episodic role in the thriller Dude Water Winner (1991) by Arkadi Tigai.

Viktor Tregubovich died on September, 21st 1992.
