Continuity mistake: When Alice and Mark are collecting all the sheets from the floor, Alice looks at a sheet about Amanda Krueger. Then in the next wide shot as her dad calls for her, all the sheets are in a pile to her right. Then in the following closeup, she starts picking up sheets of paper from all around her.
Trivia: The film was rushed into production, appearing in theaters almost exactly one year after the previous film. As a result, director Stephen Hopkins was perpetually rushed during filming and given extremely tight deadlines to meet. The studio executives were so impressed by his ability to handle pressure, that he was immediately offered the chance to direct "Predator 2."
Trivia: The idea of focusing the story around children and birth was hatched by Executive Producer Sara Risher, who was a new mother at the time, and constantly had her child and its well-being in her mind. The crew decided to build off this, because they felt that the teenagers and 20-somethings who were fans of the original film were beginning to reach the age where they were likely thinking about settling down and having families themselves. Thus, incorporating elements of family and birth into the film would keep the series relevant and special for fans of the earlier entries.
