Factual error: While Jason is practicing piano at the Dew Drop he hears the horn playing outside, then when he walks out of the back door he sees Josh on the trumpet, and in the first shot of Josh we see a blue modern vehicle moving behind the bush, at the top left corner of the screen. (00:05:00)
Continuity mistake: When Verdi is sitting on Josh's bed, talking to him about being a man, the medium shot has her face tilted to the left. But in the immediately close-up, it's suddenly to the right as she finishes her comment.
