The song "Once Upon a December" is from the 1997 animated film Anastasia (Fox Animation Studios). It was not sung by Grand Duchess Anastasia Romanov or her grandmother.
The song, composed by Stephen Flaherty (music) and Lynn Ahrens (lyrics), became a popular standard, covered by Deana Carter, and featured in the 2017 Broadway adaptation. It epitomizes the film's blend of nostalgia, loss, and hope.
The film's marketing and emotional resonance blurred lines between history and fiction for many viewers. Anastasia's tragic story invites romantic reinterpretation.
