Old movies

Been watching a lot of old movies lately. The Seven Year Itch with Marilyn Monroe, Desk Set with Spencer Tracy and Katherine Hepburn, His Girl Friday with Cary Grant. They don't make movies like this anymore. Incidentally, His Girl Friday is one of the first (if not the first) movies to have the actors "talking over each other" for a more realistic sound. Before, the actors always waited until the previous actor's lines were finished before beginning with their own. Interesting tidbit. Mr. Big looks an awful lot like Cary Grant. I think those Sex and the City casting people knew what they were doing.
