"Don't Trust Your Husband" is a 1948 film starring Fred MacMurray, Madeleine Carroll, Rita Johnson, and Buddy Rogers.
Carroll and MacMurray play a couple, Vincent and Paula Doane, who have been married five years. He's in advertising and is never home due to having to work with one Mr. Fraser. One day he says he's playing golf with Mr. Fraser. However, he leaves without his golf clubs, which Paula throws out the window.
Paula concludes there's another woman. In truth, he is trying to land an account but must deal with his ex-fiancée and doesn't want to tell Paula. Her sister-in-law (Johnson) talks her into hiring an actor to flirt with her at the anniversary dinner she and Vincent are having. Vincent finds out about it from a friend, and looks forward to it.
However, Claude Kimball (Rogers), the President of a huge tobacco company enters the restaurant, and even though the talent agent has reserved the table next to Paula and Vincent, the restaurant owner insists that Kimball must be seated there instead as it's a better table than the one where he was to be seated.
This had great potential and was good for sure, but I would have loved to have seen it with a better director and a better cast. There is nothing wrong with MacMurray or Carroll, but in the hands of, say, Cary Grant and Irene Dunne, just as a for-instance, it could have been a scream. Also it needed to be directed with a little more zip.
Enjoyable but on the ordinary side.
