Designers who worked on “Annette” told The Post the fiery-haired puppet wasn't meant to look like the actors, but that her overall spirit was inspired by the photograph of a young girl Carax knew. Annette appears as nine different puppets from birth to 6 years old, with two to eight expressions per age.

Annette is a 2021 musical romantic drama film directed by Leos Carax in his English-language directorial debut. The film's story and music were written by Ron Mael, Russell Mael, and Carax, with lyrics co-written by Carax.

The Story of Annette Zelman is a tale of love and resistance that plumbs the depths of human passion, prejudice, and betrayal. The film is based on actual events told in the book Dénoncer les Juifs Sous l'Occupation (Informing on Jews during the Occupation) by Laurent Joly.
