In His Girl Friday (1940), Grant (editor Walter Burns) is paired with Rosalind Russell (ace reporter Hildy Johnson). Together they explode with brilliant comic timing in this breakneck-speed newspaper farce. Russell totally matches Grant shot for shot.
A strange choice of poster design for the first, as it doesn't reflect the film one iota.
The second makes it seem more of a mockery than a comedy.
It's interesting to think that the original play had 'Hildy' as a man. The male Hildebrand was changed to Russell's Hildegard. So it went from a satire on the workings of a newsroom, to the fabulous duel of wits between a man and a woman, within the workings of a newsroom.
The fast speech and over-lapping dialogue make this one of the funniest films, but also one of the best depictions of the news-reporting world.
