The Hitchcock Outlier
When we think of Hitchcock, we think of showers, birds, and Cary Grant hanging off a mountain. Mr. & Mrs. Smith (often cataloged as just Mr. Smith) is the odd one out. It’s a screwball comedy, a genre that lived and died on fast talk and 'battle of the sexes' tropes.
For a parent, the interest here is purely academic. If you're doing a 'history of film' unit at home, this is a great example of how the Hays Code forced filmmakers to be creative with how they handled romance and conflict. Because they couldn't show certain things, they talked—a lot.
The Pacing Problem
Modern kids are used to a visual language that moves fast. Screwball comedies move fast verbally, but visually they can feel static. You're watching people in rooms argue about certificates. If your kid isn't already into classic cinema, this will likely be the movie that makes them ask to go back to their room and play Minecraft.
If you do watch it, lean into the absurdity of the premise. The idea that a three-year marriage could be voided by a district boundary change is the kind of 'legal glitch' that actually makes sense to kids who deal with software bugs and weird school rules.
