Yes, 'Madness' is appropriate indeed.
I'm a huge David Lynch fan - he and Stanley Kubrick were always my 2 favorite film-makers; the painter and the still photographer - when he announced a few weeks ago that he'd had emphysema for 4 years and needed oxygen to walk across his living room, I was expecting that sad news at any time.
Lynch and Kubrick were certainly mutual admirers of each other's work....
'Mulholland Dr' is my all-time favorite film. Loved 'Dr Strangelove', 'Lolita' and the rest, but my fave Kubrick would be a tie between '2001' and 'A Clockwork Orange'. It's raining, I'm singing.
