Les éditions de la Pastèque, the publishing house of the books of Michel Rabagliati sent another artist Cyril Doisneau to do a book of drawings on the 31 days of shooting of the movie based on Paul à Québec and other comic novels by Rabagliatti. The book is called '31 jours de tournage'
One of the references in the movie are the stars. Paul puts stars on the ceiling of his daughter's room. And one of the comic books he read to her is "The Shooting Star" by Hergé, part of the Adventures of Tintin.
