His Girl Friday: the original material was already rich and entertaining enough (The Front Page, by all accounts, is as close to Ben Hecht and
Charles MacArthur’s original play as possible), but Howard Hawks and screenwriter Charles Lederer made a couple of masterful changes by switching genders and adding a romantic component, which improves upon what was there already, resulting in one magnificent comedy. A ripple effect is the casting of Rosalind Russell, who is wonderful in the role, matching co-star Cary Grant’s zany energy; the whole cast is a marvel, delivering the mile-a-minute, funny dialogue to absolute perfection. Gene Havlick’s editing and Joseph Walker´s cinematography are simple, non-intrusive, at full service of the storytelling; that said, the staging is very complex and the framing often had to deal with quite a few characters at the same time.
