Sandra is played by Tim Allen's real-life daughter Elizabeth Allen-Dick.
In episode 2, the "10,228 days" on the board is the 28 years since the incident in the 1994 movie.
Tim Allen commented that one thing that bothered him from the original movie was how the elves never seemed upset about how the previous Santa vanished without warning, or what happened to the previous Mrs. Claus. The series writers explicitly worked with him to address that.
Premiered 16 years after the last film installment, Santa Cláusula 3: complot en el Polo norte (2006), and 28 years after the first film, Santa Cláusula (1994).
The first Tim Allen "Santa Clause" installment not to have Peter Boyle, who played roles in all three films, as he passed away shortly after the third film's release in 2006.
