Elizabeth Allen-Dick, who plays Sandra Calvin-Claus, is Tim Allen's real-life daughter, and the role marked her acting debut.

Jim O'Heir took over the role of Santa Claus XVII (Scott Calvin's predecessor) from Steve Lucescu, who had played the character in The Santa Clause and The Santa Clause 3: The Escape Clause.

Casey Wilson took over the role of Sara, the grown-up version of the little girl Scott first met as Santa, replacing Melissa King from the original The Santa Clause film.

Tracy Morgan was cast as The Easter Bunny, replacing Jay Thomas, who had played the character in previous films and died in 2017.

The series was initially developed under the working title 'The Clauses' as a legacy-sequel to The Santa Clause films exclusively for Disney+.

According to Tim Allen, early drafts of the show featured many otherworldly characters like ghosts and goblins, but he pushed back, insisting the show acknowledge the religious roots of Christmas rather than lean into fantasy creatures.

Filming for the first season took place in Los Angeles starting in March 2022 and wrapped in June 2022, with JP Wakayama serving as cinematographer.

Ariel Rechtshaid was announced in November 2022 as the composer for the series' score.
