Alfred Hitchcock interview (part 6 of 6) Tomorrow Show with Tom Snyder Fall 1973

Hitchcock's disdain for actors was an act, much like Jack Benny's stinginess. But I do think there was a little truth in it, not so much for acting as a profession, but in regards to stars that had placed themselves high on a pedestal with big demands, big tantrums, and big salaries. He was trying to neutralize their egos a bit.

That's an inner joke on the story he was telling in part 5. That's also an statement to clear him from being sued by someone who could've found that was an innapropriate story.

it's just his dry sense of humour

he doesn't really mean it
