(2010) is loosely based on the trilogy of Nurse Matilda books. The film does not closely follow the plot of the trilogy, but several individual scenes are derived from the three books. Emma Thompson started to write the script, based on Brand's books, in the spring of 2007. Although a third film was originally planned, as Emma Thompson stated previously in an interview on Friday Night with Jonathan Ross, the box office returns from the second film were determined to be too low to proceed with the third film.
