Just like Downton Abbey, the movie Belle follows an aristocratic family, their daughters, and those girls' romantic complications. The catch? The daughters are adopted cousins, cared for by their aunt and uncle, and one of the sisters is a biracial aristocrat in the 1700s. Based loosely on the true story of Dido Elizabeth Belle Lindsay, the movie explores a changing era with all the opulent production values and swoon-inducing romance you can ask for.
