This screen adaptation of the Ben Hecht and Charles MacArthur play "The Front Page" was adapted for the talents of Cary Grant and Rosalind Russell -- there is no such character as Hildy Johnson (Russell) in that play.
Director Howard Hawks wanted to show the whirlwind pace of the newsroom in the criminal courts system so he had his actors overlap their lines -- so much so that at times it seems as though everyone is talking at once; it even gets difficult to understand all that is going on.
He also had the cast move FAST so the film looks totally frenetic from scene to scene with no respite -- either from the laughs or from the action.
There are two really good "inside" jokes in the script: The first is where Walter Burns (Grant) is describing Hildy's fiancee and says that "he looks like that guy in the movies -- Bellamy," Well, it WAS Ralph Bellamy playing that part!
The other is when Burns says something about someone he once knew named "Archie Leach" which just happens to be Cary Grant's real name.
This is one of the true gems of Hollywood's most prolific era. It has incredible pacing, acting, photography and an authentic gritty feeling that would be associated with hard-boiled, "anything for a story" newspaper people.
It has long been one of my favorite films and deserves to be watched over and over again -- just for all the dialogue and great acting that may have gone by so fast you missed it the first time.
