Trivia: Star Ariana Richards is given an "introducing" credit despite it being the fifth film to feature her. She later clarified that it technically was her first film, but the production ran long in part due to the effects, and four other films she worked on came out first.
Trivia: Royal Dano plays a goofy old man who encounters aliens with his dog. Two years prior, in "Killer Klowns from Outer Space," he similarly played a goofy old man who encounters aliens with his dog. (Albeit, his fate in that film was much different than in this film.)
