Dennis Weaver reads an article about a house "made entirely out of bottles". His own famous home was made out of recycled tires, cans and bottles.
Oliver Robins, who plays Kevin in this movie, starred in another horror movie of the same year, Poltergeist: O Fenômeno (1982).
The address of the house the family moves into is 13666. Traditionally, 13 is the number of the bad luck and misfortune, which it is attempted to avoid (i.e. hotels and skyscrapers don't have a 13th floor, ending in the 12th or "jumping" from 12th to 14th), after Last Supper where Judas Iscariot (the 13th apostle) betrayed Jesus to the Roman Empire. 666 is the alleged number of The Beast, Satan's son, Antichrist (opposite to Jesus).
