If you loved Song of the South, try Lady and the Tramp
A bridge between a film you've already seen and one most people haven't. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Wilfred Jackson, and they sit in Animation / Family territory. If that's the register that drew you to Song of the South, the second film will land in a comparable space — through a different lens.
What Lady and the Tramp is
It seems romance can be ruff. Lady, a pampered spaniel, joins a street dog. The film somehow makes canine love work.
