The video was made available recently by 5TV, a Russian television channel formerly known as Leningrad Television.
Fans can now watch the film in its entirety in two parts, for a total duration of about an hour and 50 minutes.
The movie, whose title translates to Keepers, was released in 1991 – 10 years before the first instalment of Peter Jackson’s trilogy. It was directed by Natalya Serebryakova.
According to The Guardian, the movie is believed to have aired only once at the time of its original release, remaining unavalaible to most for years afterwards.
Meanwhile, a new adaptation of The Lord of the Rings is in the works at Amazon. The studio teased details in a synopsis earlier this year, saying the series will act as a prequel set before Jackson’s trilogy, and will feature some “familiar” characters.
