In this likable movie yes: He is. And also cast against type is the title character. Evelyn Keyes wrote one of the very first racy autobiographies and was married numerous times, to exciting men. Yet here she is a stern businesswoman. And her nickname is Butch! The title itself sounds like the title of a monograph my for an animal husbandry course. It couldn't be less romantic. Indeed, Millie's reason for wanting to be -- well, mated is originally not romantic at all. She wants to adopt a neighbor's child.
She thinks Ford would be a good husband, which she learns she must have. But she finds two other suitors. They seem quite unlikely, as cast.
The movie is fun and stylish. Keyes is fitted out in the most unrevealing clothes imaginable. This is true even when she is glamorized. They're pretty but look like slimmed-down versions of clothing Margaret Dumont might have worn.
