Well, technically, it’s a 96-minute press conference moderated by film historian, author, and critic Richard Schickel. However, it really is a bit of a masterclass as Alfred Hitchcock, quite confident in what he does and doesn’t do, gives pronouncements about how he goes about things.
Note that you may want to watch Family Plot, his last film, before watching this as that’s the reason for the press conference. You may also find that he’s rather old school and private in his answers, compared to what you might expect from a modern talk show. That should in no way distract some great nuggets of wisdom as to how he approaches filmmaking as a craft. I especially appreciated his observation on keeping the audience engaged and, above all, not confused.
Also, a pro-tip from the comments. If you play the video at 1.5 times speed (under the settings menu in YouTube), you’ll finish faster and Hitchcock will, frankly, not sound like the spokesman for the Slow Talkers of America (which he clearly isn’t, what with being British and all).
