Helfgott's sister Margaret Helfgott, in her book Out of Tune, stresses in particular the case of Helfgott's father Peter Helfgott, who was, according to her, a loving husband, over-lenient parent and very far from the abusive tyrant portrayed in Shine.
Helfgottova sestra Margaret Helfgott u svojoj knjizi Out of Tune posebno ističe Helfgottovog oca, Petera Helfgotta, koji je, prema njezinom mišljenju, bio sjajan suprug, brižan roditelj i daleko od zlonamjernog tiranina kakvim je prikazan u filmu.
