Random Trivia For This Title:
- In the original ending, Kevin's parents did not get back together. His father stayed with Natalie, and his mother started dating a police officer who turned out to be Marv's younger, more honest brother. This was changed when the producers decided they wanted the film to set up a TV series, and so Kevin's parents did get back together at the end, while the police officer was deleted altogether from the script.
- The producers had hoped that this movie would lead to a [Home Alone] TV series, and several of the main cast members had clauses in their contracts that would have bought them back for such a series. This movie failed to perform up to expectations in the ratings, though, and the series never went ahead.
- Daniel Stern, who played Marv in the first two films, was approached to reprise his role in this one. Stern quickly declined, calling it "an insult, total garbage."
