It's a wonder that the "Memorable Quotes" pages of the IMDb entry for His Girl Friday doesn't just reproduce the entire script, you know? Of course, the only way to represent on the page the speed at which the sparring dialogue between Cary Grant and Rosalind Russell [with the Greek chorus of hardbitten newspapermen and, don't forget, Mother] is rattled off would be to fill every centimeter of white space with words.
But now, instead of looking it up, you can watch the whole thing online. The film, which has passed into the public domain, has been uploaded to archive.org and is just waiting there for you to stream or download. There's also a pretty impressive collection of thumbnails, one from each minute of the film, so you can admire Hildy's impossible hats from every angle.
