Alien Nation: Dark HorizonGoofs

Cathy's spots are noticeably different from their appearance in Alien Nation (1989).

Although this is a continuation of the series' final cliff hanger, the scene where Susan and Emily are poisoned, and the scene where Cathy tells Matt about it, are completely different.

When George and Matt are singing to Susan in the hospital, you can clearly see Matt trying to stifle a laugh several times.

When Ahpossno is getting ready to leave the spaceship, the commander erases his Overseer tattoo. But when he arrives on Earth and sees the homeless Newcomer, Ahpossno show his tattoo.
