Back to the topic of the thread, and apologies for joining it so late:
Blow Up is considered by some film critics to be a signature film in the growth of the suspense movie, despite its occasionally pointless sideplots. It was, in fact, nominated for two Academy Awards: Best Director, and Best Original Screenply. If you've ever seen Mel Brook's HIGH ANXIETY, Blow-Up is spoofed as evidence of a North-by-Northwest style murder is found on a print about 3 meters on a side. (10 feet, for my fellow Yankees.)
Also, check out this review of Austin Powers (the first, and in my opinion the best one) by Roger Ebert:
"The movie, written by Myers and directed by Jay Roach, is smart enough to know the 1960s are funny without being exaggerated. In one sequence, a fashion photographer shoots '60s fashions, and the clothes, which look like outlandish science-fiction fantasies, are in fact identical to costumes worn during posing sessions in Antonioni's ``Blow Up'' (1967)."
