Best music movie mistakes of 1996

Continuity mistake: In the first scene where we see David Helfgott, there's a mark on his ring finger, probably made by a wedding ring. In that scene David isn't married.

Factual error: When The Oneders are recording their song with Uncle Bob, there is an In-N-Out cup sitting by the recording equipment. There are no In-N-Out restaurants in PA.

Duffman

Other mistake: Carolyn Stilton shoots Blondie O'Hara in the head and is lying dead over her dead husband. Just before the final scene starts she begins to open her eye.

Plot hole: There's no way for Albert to show up at the front door as Val's mother the night the Keeleys are there, as the only way out of his bedroom (which he is still in by the time the Keeleys show up) is through the door that leads into the living room where the Keeleys, Val and Armand are.

Visible crew/equipment: When Jim gives his donation to Danny just after Gloria walks into the practice room for the first time, a microphone can be seen reflected in his tuba bell.
