Hidden Mickey: When Tinker Bell climbs the book shelves, when she looks down, the mushroom table & chairs are in the trademark Mickey Mouse shape.
Mae Whitman (Tinkerbell) and Lucy Hale (Periwinkle) both played the younger sister of Jamie Sommers in Bionic Woman (2007). Lucy Hale took over the role when the first unaired pilot was revamped.
In the "Sneak Peak" on the previous Tinker Bell installment, this film is called "Tinker Bell and the Mysterious Winter Woods".
Jeff Bennett (Dewey, Keeper of fairy knowledge) channels Tim Conway's Mr. Tudball from The Carol Burnett Show (1967).
AnnaSophia Robb was originally cast in the role of Periwinkle.
