In case you have any doubt as to the meaning of the title, I'll put you out of your misery: Prudence and the Pill is about the birth control pill. It's a hilarious British comedy starring David Niven and Deborah Kerr that proves you can get pregnant even if you think you're too old, and even if you think you're on the pill.
In the 60s, it wasn't as commonplace for women to be on the birth control pill as it is today-or was it? As David Niven's maid's boyfriend hides birth control pills in her vitamin bottle-so as to not insult her by suggesting she prevent a pregnancy-the maid switches her vitamins, which are really birth control pills, with Deborah Kerr's birth control pills, which are really just vitamins. Why are they vitamins? Because David and Deborah have a marriage in name only; they each have extramarital affairs, and in order to get a divorce and marry his mistress, David wants to prove his wife's infidelity. He switches her pills with vitamins-what's a better proof of infidelity than a pregnancy?
The plot is fast-paced and a little complicated, but if I didn't get confused, you won't either. The humor is very British, but I found it absolutely hilarious. If you like British comedies, you'll absolutely love this one. It's a sex comedy with references rather than raunchiness, so it's classy and funny and sexy all at the same time-just like David Niven! I love him anyway, so I was a little predisposed to like this movie, and it shows off his comedic talents wonderfully. Also, I know Deborah Kerr was more famous for her meaty dramatic roles, I actually like her better when she's being funny! Give this one a try and see which side of her you prefer.
