The movie was a rarity in that it was filmed in the USA by a small core Russian production team from the Soviet Union.
According to an interview with Anne Carlisle in the July 1984 edition of Moviegoer Magazine, the movie was the most successful independent film of the 1983 year grossing $1.7 million at the box-office in the film's first months of release.
According to the movie's official site, the picture spent twenty-eight weeks on Variety's top grossing films box-office chart and was the longest running title on it for the year of 1983.
The movie's "Liquid Sky" title is a phrase which is a slang term for heroin.
Only four members of the crew (the director, his wife, the cinematographer and the camera operator) were Russian. Everyone else was American.
