Continuity: The length of David Helfgott's cigarette when playing "Flight of the Bumblebee" at Moby's.
Anachronisms: Aluminium roller shutters on the Helfgott family home.
Factual errors: The mezzuzah, a Jewish religious scroll attached to a home's door posts, on Ben Rosen's home is angled the wrong way; it should be angled toward the entrance of the home.
Factual errors: In the film, the character shows all signs of schizophrenia; not bipolar disorder (formerly known as "manic-depressive disorder"), as is claimed in the film. Furthermore, David Helfgott, in person, displays many symptoms of schizophrenia and none of bipolar disorder.
