Dolly Madison is a truly fascinating character from American history. Unfortunately, while "Magnificent Doll" does center on her life, it also is filled with historical inaccuracies...enough so that it's not a particularly good history or civics lesson. The biggest problem is that romance between Madison (Ginger Rogers) and Aaron Burr (David Niven) as I could find no indication that they ever dated or had any sort of relationship apart from taking a room at her mother's rooming house. There also is no mention of a child from her first marriage...one that did NOT die from Yellow Fever. And, sadly, what we know Dolly DID do was generally omitted or given only brief mention.
Apart from the inaccuracies, the film is a mildly entertaining but occasionally stuffy film. In particular, the latter portion of the movie seems to go off the rails...and boredom set in as I watched. Not terrible...but Dolly sure deserves better than this tepid plot.
