His Girl Friday (1940)

One of the all-time classic screwball comedies, directed by Howard Hawks and starring Cary Grant and Rosalind Russell. A newspaper editor (Grant) tries to win back his ex-wife and star reporter (Russell) by suggesting they work together on one last story. Based on the classic 1928 play The Front Page, which has been adapted for the screen four times, though this version is considered the greatest.
