Motives for the script
Controversy has dogged The Illusionist, with it being reported that "Tati was inspired to write the story in an attempt to reconcile with his eldest daughter, Helga Marie-Jeanne Schiel, whom he had abandoned when she was a baby. And although she's still alive today and may in fact be his only direct living relative, she is nowhere mentioned in the dedications, which has seriously annoyed some".
In January 2010, The Guardian published the article "Jacques Tati's lost film reveals family's pain" stating, "In 2000, the screenplay was handed over to Chomet by Tati's daughter, Sophie Tatischeff, two years before her death. Now, however, the family of Tati's illegitimate and estranged eldest child, Helga Marie-Jeanne Schiel, who lives in the north-east of England, are calling for the French director to give her credit as the true inspiration for the film. The script of L'illusionniste, they say, was Tati's response to the shame of having abandoned his first child [Schiel] and it remains the only public recognition of her existence. They accuse Chomet of attempting to airbrush out their painful family legacy again."
On 26 May 2010, renowned film critic Roger Ebert of the Chicago Sun-Times published a lengthy letter from Jacques Tati's middle grandson, Richard McDonald, that pinpointed historical events in the private life of Jacques Tati that the family believe were his remorseful, melancholy inspiration to write, yet never make, L'Illusionniste.
Chomet has a different opinion about the film's origins, although acknowledging: "I never got to meet Sophie, or even speak to her about the script." Chomet said, "I think Tati wrote the script for Sophie Tatischeff. I think he felt guilty that he spent too long away from his daughter when he was working."
In a June 2010 interview for The National, Chomet gave his personal reasons for his attraction to the script: "I have two young children, a four-year-old and a two-year-old. But I also have a daughter who is 17 whom I don't live with because I separated from her mother. She was 12 when I started the project and you can feel things changing." This appears to mirror the regret of a broken paternal relationship that Tati had with his own daughter Helga Marie-Jeanne Schiel. Of the story, Chomet commented that he "fully understood why [Tati] had not brought [The Illusionist] to the screen. It was too close to him, and spoke of things he knew only too well, preferring to hide behind the figure of Monsieur Hulot".
Having corresponded with Tati's grandson, former Tati colleague and Chicago Reader film reviewer Jonathan Rosenbaum published an article entitled "Why I can't write about The Illusionist" in which he wrote, "Even after acknowledging that Chomet does have a poetic flair for composing in long shot that's somewhat Tatiesque, I remain skeptical about the sentimental watering-down of his art that Chomet is clearly involved with, which invariably gives short shrift to the more radical aspects of his vision". With McDonald being quoted saying, "My grandmother and all his stage acquaintances during the 1930s/40s always maintained that [Tati] was a great colleague as a friend and artist; he unfortunately just made a massive mistake that because of the time and circumstances he was never able to correctly address. I am sure his remorse hung heavy within him and it is for this reason that I believe Chomet's adaptation of l'Illusionniste does a great discredit to the artist that was Tati."
