Trivia / One Fine Day

• Cast the Expert: Pete Hamill, a reporter/novelist who was working for The Daily News at the time, plays a rival reporter of Jack's.
• Throw It In!: Maggie forgetting the kitten's name was not in the script - it was Mae Whitman forgetting the name - but director Michael Hoffman liked the moment and kept it in the final cut. Similarly, Michelle Pfeiffer running into the table in her apartment near the end of the movie was unscripted.
• What Could Have Been: Tom Cruise was originally considered for Jack, but turned it down.
