A 1958 British courtroom drama. A snotty rich guy takes his wife to divorce court. He's sterile, he didn't want to adopt, so the couple resorted to artificial insemination. Then he turned on his wife and argued in court that artificial insemination is "adultery".

And they had wartime rationing back then---he and his friends squandered what little gasoline they were allotted to see that thing.
