When watching the Netflix movie, Falling for Christmas (2022), Kathy comments, "That looks like a girl I went to high school with." Lacey Chabert, who plays Kathy, starred in Mean Girls (2004) with Lindsay Lohan.
Dustin Milligan said he drew inspiration from Will Ferrell in "Elf", Daryl Hannah in "Splash", Jennifer Garner in "13 Going on 30", and Tom Hanks in "Big" when preparing to play Jack.
When dismissing a theory that Jack actually came to life, Kathy remarks "Yeah, sure, and I'm the queen of Aldovia." Aldovia is a fictional European country and setting for the holiday movie trilogy A Christmas Prince (2017), also produced by Netflix.
Dustin Milligan (Jack) said this was the most fun he's had working on a project.
