Journey Through the Black Sun

Set after the Moon has been flung into deep space, this film weaves two connected Space: 1999 season one episodes into a single, extended crisis. When a colossal object and a strange dark stellar phenomenon loom near Moonbase Alpha, the crew scramble to assess threats and protect the population. Commander John Koenig leads emergency operations while Doctor Helena Russell tends to the wounded and Professor Victor Bergman tries to work out the science behind the menace. Captain Alan Carter handles high-risk maneuvers and pilot duties, and the arrival of the enigmatic Arra adds a human and political complication. The story emphasizes tense problem-solving and ethical tradeoffs without revealing how events resolve.

Released in 1982 by ITC New York, the feature was directed by Lee H. Katzin and Ray Austin, and assembled from scripts by David Weir and Anthony Terpiloff for Space: 1999.

Rather than enjoying a major theatrical run, the production functioned mainly as a TV-episode compilation for syndication and some international markets, so it lacks notable box office figures and is best known through television broadcasts and home video.

As a repackaging of television material, the film helped keep Space: 1999 in circulation during the 1980s and fed the series' cult following. Fans of Martin Landau and Barbara Bain point to memorable set pieces and the eerie "black sun" imagery, and the movie has appeared in retrospectives about genre TV being reformatted for wider distribution.

Audience and critical responses have been mixed, reflected in a modest 6.2/10 user score on a small sample of votes. Viewers often comment on the film's themes of isolation, decisive leadership under strain, and the collision of scientific curiosity with urgent survival needs, while some note that episodic pacing still shows through in the combined format.
