|Constance Bennett||Duchess of Florence|
|Fredric March||Benvenuto Cellini|
Benvenuto Cellini is a goldsmith, artist, womanizer and swashbuckler known throughout Florence, Italy. When he enters the royal palace of the Medicis, he instantly has eyes for the Duchess of Florence, who openly returns his ardor. The dithering, dim-witted Duke barely notices because he's too besotted with an airhead model . However, when Cellini gets too cocky, he suddenly finds himself flirting with execution.
