I've read the two most influential Broadway comedies where What Price Glory? and The Front Page - certainly it's easy to see the influence of the latter on journalism movies. This remake would be highly influential on rom coms.
Every change improves it - making it a romance, giving the journos more humanity, bringing in Walter and Hildy to start.
Cary Grant and Rosalind Russell have the time of their lives, Ralph Bellamy is perfect. Wonderful cast and film. The Nazi-Soviet pact at the time meant the anti-commie jokes could be kept.
