Brother Bear (2003)

About twenty-four minutes in, the narrower, slightly muted frame of Kenai's human life opens out to 2.35:1 widescreen, and the palette turns bolder and more vibrant. The wider world arrives at exactly the point where his way of seeing it changes, and nothing beforehand hints that it is coming. It's the easiest entry here to share with children, who tend to notice the bigger picture without needing it explained. On disc, the opening section is boxed with black bars on all four sides; that is the intended presentation, not a fault.
