Look, it isn't right to exclude everything he didn't direct personally. He was a control bug like lots of other directors, and even took a hand in the screenplay writing. He would describe scenes and dialogue so closely to his script writers that they almost became stenos at times -- he had very strong inputs at all levels. Just because he didn't direct an episode, doesn't mean he wasn't fully involved, esp. when eyewitness recollections say he tended to exert very firm and comprehensive control.
Now if he actually walked away from his TV project at some point, then that's different, but I'm not aware he did. And several of the episodes as I've described them did use Southern characters, tho' I'd have to find the one episode that I do remember strongly, and I think it was one of this series (that, or some film you didn't list -- ?), that presented that "cracker" stereotype. And I've read elsewhere that he had very strong likes and dislikes (he was very afraid of policemen and sirens and found several references, including quotes on IMDB.com, to those fears and dislikes; and he hated eggs, loathed them), and that Southerners were among them. No, I didn't see any big analysis or breakdown, no attempt at sidewalk psychoanalysis as in the case of some of his other tics (as about policemen, which went back to an episode precipitated by his father in collaboration with a local police booking sergeant). Just the statement, which I put together with that episode or film or whatever it was of his that I'd seen. And he had a lot of marked tics -- he wouldn't tolerate extraneous people on set, and had eyes in the back of his head -- he once had a person ejected from a set, without ever looking to see if that person was actually there (this was a first-person eyewitness recollection I saw on TV ages ago). And so on. He was actually a bit creepy.
s So I'm not giving up on the point, I'm not going to bend or break, so flame on, I know where you're coming from and I'm not going to enable your grift.
Especially after seeing Pumpkinhead tonight on late-nite TV. What a classic (not!).
So what's next on your Netflix list? Texas Chainsaw Massacre? If so, which version? So many choices .....
Except that those eyewitnesses are talking about his feature film work. His role in the TV series was much more limited because he was directing the features at the same time:
For support, Hitchcock turned to someone he could trust: Joan Harrison, who had worked on screenplays for several of his movies in the 1940s, would produce the series, with actor/director Norman Lloyd serving as associate producer. Hitchcock’s involvement with episodes he did not direct was fairly limited: He would review the stories briefly and watch screenings of the finished episodes; reportedly, he had two responses to the screenings. He would say either “That was interesting,” meaning he liked it, or “thank you,” meaning he did not.Even if this episode you decribe exists (and frankly, it sounds more like an episode of Boris Karloff's "Thriller"--"Pigeons from Hell" maybe), the presence of one episode perpetuating a stereotype you don't like, out of a pool of 363 episodes, hardly constitutes evidence that Hitchcock himself "hated southerners with a passion" except, of course, to someone like you who is looking for any slight to reinforce your persecution complex.
So what's next on your Netflix list? Texas Chainsaw Massacre?
Actually the next two things on my Netflix list are "The White Ribbon," a German film, and "The Last Station," a film about Tolstoy's last days, both of them Oscar nominated last year.
