Margaret Helfgott's criticisms have been disputed by people involved with making the film. Scott Hicks published a letter to "The Wall Street Journal" when Margaret Helfgott's book came out, defending the authenticity of the movie's portrayal of Helfgott's childhood and suggesting that David's other siblings, Susie and Les, were at odds with Margaret's claims and were happy with the movie. John Macgregor—who was involved in the research and wrote the treatments for "Shine"—wrote, in a letter to "The Australian", that the portrayal of the Helfgotts' father was supported not only by David's 'elephantine' recollections, but (with the exception of Margaret) by every family member and family friend he and Scott Hicks interviewed, as well as by every interviewee who had a professional or musical connection with David throughout his early life. However, David's brother Les has described the portrayal of their father in both Shine and in Gillian Helfgott's biography as "all outright lies". David Helfgott's first wife Clare Papp has also said that Peter Helfgott was "quite badly maligned" in the film. In a letter to the editor of Limelight magazine, published in the September 2013 edition, Margaret and Les Helfgott refer to certain claims made in an article in the August 2013 edition and state that "there was no estrangement from members of David's family following his return to Australia. On the contrary, he moved straight back into the family home, and was cared for by our family. Dad was not 'overbearing', and his main objection to David's going abroad was his concern for his son's welfare."
