Trivia: While "A Cold Day in Hell" was filming, Kevin Bacon, who co-starred in the original film, was working on a pilot for a "Tremors" TV-series, as he had long wanted to return to the franchised, but wanted to to move it to episodic television. Unfortunately, shortly before this film was released, the series was passed on by the intended network. Around the same time, co-star Michael Gross announced that Universal was already interested in producing a seventh film, should this sixth film be successful.
