1942's "Take a Letter, Darling" is a fun look at life in the '40s, and no one could play a career woman like Rosalind Russell. Tough, intelligent, sophisticated and glamorous, she fits easily into a man's world. In this film, directed by Mitchell Leisen, A.M. MacGregor (Russell) is the active partner in an advertising firm with Atwood (Robert Benchley), but she has both man and woman trouble. Men make passes and wives are jealous. To get around this, she hires a male secretary, Tom Verney (MacMurray) who in reality is an artist trying to save money to move to Mexico and paint. He takes notes, does research for her and, most importantly, poses as her fiancé at business dinners.
Verney is wary of the job from the beginning and plays along reluctantly. When A.M. learns the often-married Jonathan Caldwell (MacDonald Carey) is looking for a new advertising company for his tobacco company, she also learns he hates women. She maneuvers a meeting but learns that his sister (Constance Moore) has to approve the campaign. Enter Verney - but when the sister turns out to be young, beautiful, and invites Verney to the southern plantation - A.M. finds she's jealous.
Good movie, good fun, terrific cast, if somewhat predictable.
