The basic tenet of horror movies – "˜ Nothing is as it seems "˜ and for me, Don't Look Now is a death of all certainties.
In the early seventies, when even mainstream films could be fearless and experimental, smashing taboos and taunting the censors, it was non-conformists who offered cinemagoing a uniquely intense experience.
 “Don't Look Now 1973 retains its power and mystery today thanks to Roeg's mastery of what Alfred Hitchcock famously called "pure cinema," manifest in his visual sleight of hand and, above all, in his refusal to be bound by the conventions of dialogue-driven narrative and simple chronology. All this has shaped a style that has justifiably come to be described as "Roegian."– (David Thompson: Seeing Red 2015 article CRITERION )
“Nothing is what it seems," says John Baxter, the protagonist of Don't Look Now, at the start of the film. The rest of the movie depicts the tragedy of Baxter's incapacity to apply this fundamental wisdom in his own life. "Nothing is what it seems" may be an untested platitude, but it's a truism when it comes to movies, and Don't Look Now is one of the great "movies-about-movie-watching" ever made. Primarily, it is about the act of perception itself"¦ By seeing an event that has not yet happened as something that is already happening (what-will-be as what-is), he (John) fatally confuses the signs and makes the future the past, i.e., irrevocable, inescapable. Like a movie stamped on celluloid, or the glimpse of the satanic dwarf on the slide Baxter is handling in the opening scene, he fixes something in time, and thereby turns life into death.""” (article – Jasun Horsley Cinephilia and Beyond)
"He was a genius, Nic. A visionary. He made a love scene between a grieving wife and herhusband with no cries of passion, no sounds of orgasm, no words. All you hear is Pino Donaggio's music as Nic intercuts their making love with them getting dressed to go out to dinner. Magical. You don't see that scene as a voyeur. You watch it and it reminds you of yourself, of you being loving and you being loved. We decided it would be wisest not to shoot John's death scene until we'd done everything else, in case the unreliable prop knife failed and my throat would be cut, spilling red. Fragmented, abstract images colour and tell his stories. Look at Omar Sharif on a camel, coming from the other end of the desert towards the camera. That's Nic. Look at the Sahara's empty foreground and suddenly the smokestacks of a steamer crossing from left to right along the unseen Suez canal. That's Nic. He was the was the first to use Panavision's R-200°, which meant he had 15 degrees more shutter for Don't Look Now than the 185°s that were the best before. He was everything I ever wanted from a filmmaker. He changed my life forever. Francine and I asked him if we could name our firstborn after him. He said yes. Our glorious son is named Roeg." - (Interview – Donald Sutherland)
