Requiem For A Dream is Darren Aronofsky’s follow-up to his astounding debut movie Pi – the lo-fi, black-and-white tale of madness and mathematics that was made for $60,000 and shot guerrilla-style on the streets and subways of New York City. It’s also an adaptation of the seminal 1978 addiction-themed novel of the same name by Last Exit To Brooklyn-author Hubert Selby Jr., a writer whose prose-style pulls no punches with the 31-year-old director.

"After I read his books I feel like I have a fist indentation in my solarplexus for about three weeks," he admits, smiling. "And I wanted to share that with all you guys." Darren Aronofsky, it would seem, enjoys the idea of being a cinematic pugilist.

Co-written by Aronofsky and Selby himself, Requiem For A Dream charts the parallel, addiction-fuelled narratives of TV junkie Sara Goldfarb (Ellen Burstyn), her drug addict son Harry (Jared Leto), his fashion-designer girlfriend Marion (Jennifer Connolly) and his dealer best friend Tyrone (Marlon Wayans). Set in New York, in the decaying holiday resort of Coney Island, it’s a disturbing film about the lengths people will go to escape their reality. Each character is addicted to the image of a better life and it was this idea, rather than the prospect of making a film about drugs, that hooked Aronofsky on the story.

"What’s brilliant about Selby is that he shows us that anything can be an addiction to fill that hole when we’re trying to escape reality. It can be TV, it can be coffee, it can be sex, it can be someone saying ‘I love you’. I wasn’t really interested in junkies and the word heroin is never mentioned in the movie. So for me, it was really about how anything could be a drug."

The film is unrelenting in its portrayal of the physical, emotional and psychological hell associated with addiction and its cinematic punch is provided by the director’s wildly inventive visual style. Building on a fast-cutting, sampling technique he started in film school and developed in Pi, Aronofsky and his editor Jay Rabinowitz created a series of what he calls "hip-hop montages" to convey the extent of each character’s addiction. "The idea was just sampling images and sounds to help tell the story and push it forward," he explains. "I grew up in Brooklyn during the eighties and the golden age of hip-hop; before Eminem. As a kid I was a really bad graffiti artist and a really bad breakdancer but I still wanted to take some hip-hop ideas and apply them to narrative filmmaking. So that’s where all the fast cutting came from. It just happened to work really well with the idea of obsession and addiction."

The end result is probably one of the most effective (if unintentionally) anti-drug films ever made. There is no catharsis for the characters in Requiem For A Dream. No one recovers, nothing works out and its impact is as horribly compelling as a road accident.

This was a deliberate ploy by Aronofsky who was bored with American cinema’s addiction to happy endings. "Hollywood has sort of killed the tragedy," says the director. "It doesn’t really exist in cinema anymore. Evens in so-called darker films – especially in a lot of drug movies – so many people recover and get out alive. And anyone who has been on the planet for 15 or 20 years generally knows that that’s not going to happen."

Instead, Aronofsky hopes that Requiem For A Dream will be about the catharsis the audience will have when they realise that their lives are "not as fucked up as these peoples’."

It was undoubtedly this insistence on tragedy that made Requiem For A Dream a more difficult second feature for its writer-director than it should have been. After winning the Director’s Award at the 1998 Sundance Film Festival with Pi, Aronofsky immediately became a hot property and when that film went on to become an unexpected commercial success, financiers told him, "What ever you want to do now, we’ll do it." He promptly sent out the script for Requiem For A Dream and not one person called him back.

"That’s a true story," Aronofsky says reflecting on his first encounter with the fickleness of the movie industry. "It was a real struggle but [my] producer, Eric Watson, said, ‘whenever everyone is telling you no, you know you’re doing something right.’ So it’s a victory to have this film done."

It’s unlikely he’ll have to struggle with his next couple of films in quite the same way. Aronofsky has been confirmed as the writer-director of the next Batman movie on which he is collaborating with Dark Knight Returns-creator Frank Miller. It’s a prospect that has the fanboys drooling at the mouth, especially after the last two kiddie-oriented cinematic outings for the Caped Crusader were so roundly despised.

Before that, however, he’s working on a remix album of the Requiem For A Dream soundtrack with its composer Clint Mansell, the former Pop Will Eat Itself front-man who also provided the atmospheric, techno-laden score for Pi .

Film-wise he’s going to make the movie that he’s been writing for most of the last year. "I’ve been pitching it as a post-Matrix, metaphysical science fiction film." He smiles. "That sounds kinda cool, right?"

Yes it does. Just don’t expect to feel too good after seeing it.
