The actors are interesting people: David Hemmings (also on Dario Argento's "Profondo Rosso", Deep Red, the scariest film I ever seen), the English (and not french :) Jane Birkin (first frontal nude at cinema), Vanessa Redgrave, and my favourite musician, the immense Jimmy Page (and Noel agrees :)
My favourite director is Alfred Hitchcock, and there's a bit of him in Blow-up, some mystery, and also a bit of Swinging London which reminded me of Carnaby Street and Pretty Green.
The final scene in a field is meaningful, as the Beatles said: Strawberry fields, nothing is real.
Blow-up also inspired Brian De Palma film Blow Out with John "Tony Manero" Travolta :)
"I thought you were supposed to be in Paris"... Veruschka, model on drugs: "I am in Paris" ahahaha
