The alien ship that lands is called the Gruza. "Gruza" is a Russian word that means "cargo".

The flashbacks to Sgt. William "Tuggs" Tuggles' death were clips from Alien Nation (1988) mixed with newly shot footage of Gary Graham in place of James Caan as Matt Sikes (spelled Sykes in the film). Roger Aaron Brown, who played Tuggs in the film, did not return for the series and only appears in archive footage. As such, Sikes and Tuggs are never seen on screen at the same time.

The film takes place in 1995.
