'Dark Matter' was supposed to be released at about this time last year, but then the Virginia Tech massacre happened and producers pulled the plug.
The film is now ready to be released.
Although 'Dark Matter' is not based on Virginia Tech, it will remind the viewer of the tragic events that happened April 16 2007 and the producers were worried that audiences would respond badly to a film about a university student killing his classmates and then himself.

In its 90-minute duration, the film grapples with a number of weighty themes: the origins of the universe, the importing of Chinese scholarly talent by American universities, even the deep causes of incidents of campus violence, like those at Columbine and Virginia Tech. But ultimately, the film's approach to these issues is as suspect as an American movie star going through the motions, however gracefully, of the thirteen postures.

Based loosely on the story of Gang Lu, a physics graduate student at the University of Iowa who killed five people and paralyzed a sixth in 1991 out of academic jealousy, "Dark Matter" follows Liu Xing, a cute but furtive student from Beijing who arrives at an unnamed American university to work under his hero, cosmology theorist Jacob Reiser. As played by Aidan Quinn, Reiser is a self-absorbed celebrity-academic, less concerned with the higher aims of scholarship than with furthering his own research by milking data from his hard-working Chinese students.

This film will definitely cause some discussion about whether it is ever the right time to release a film like this, but perhaps it will show how and why these events occur and shed some light on the first anniversary of the worst school massacre in US history.
Reviewers are doubtful however.

What is probably more to the point is that "Dark Matter" is too slick and simplistic to make much point about its subject at all. Like its vague astrophysics, its treatment of its characters and their motivations is too fuzzy and superficial to offer any real insight into situations like those at Virginia Tech or University of Iowa. Like Liu Xing's ideas about dark matter, it comes off as little more than pure speculation.
