This is perhaps the best example where one can only reply with the 'only at this very moment' intuition -
tomorrow it'd be different, I am certain.
I chose: Rebecca, Strangers On A Train, Shadow Of A Doubt, Vertigo, and Frenzy.
All fantastic. I recall Leslie Halliwell being very unkind to Marnie and Frenzy. That was his loss, although I can understand where he came from.
Frenzy has much delicious and very black humour. It is unfair to call it an 'old man's sex suspenser', as good old Leslie did. Frenzy is very much of its time, it's absolutely not erotically exciting. I'd say it's sort of a joyful deconstruction of a genre, and of a period when 'personal liberation' was all the rage.
But hey, we're talking one of the top 5 directors in my book.
..and why not?
