Concrete Playground Meets Danny Boyle and the Cast of Trance

"What is this kind of film?" This question is not, as one might expect, asked by a journalist following a screening of Trance, or by a member of the public curious about the billboards currently filling London. Rather, it is asked by Vincent Cassel, one of the film's leads, to a room of six reviewers, including myself. None of us are able to answer him.

Trance is the latest Danny Boyle film and, as such, one must approach it with very few specific expectations. Boyle has treated his career like a pick-n-mix, filling his directorial bag with genres as diverse as black comedy (Shallow Grave, 1994), Bollywood-inspired coming of age (Slumdog Millionaire, 2008) and zombie flick (28 Days Later, 2002). So what has he attempted this time?

When asked, Boyle is vague. "You tend to talk in genres when you're doing publicity but it's not really something we think about." This seems unlikely and yet the three core cast — James McAvoy, Rosario Dawson and Cassel — agree. Trance defies easy categorisation.

The film's opening minutes feel like a classic heist movie, as a high-priced work of art is stolen from the London auction house where McAvoy's character, Simon, works. It very quickly descends into violent gangster flick as Cassel's Franck, a French crime boss, enters the story. And just as quickly, it makes the switch to psychological thriller with the introduction of Elizabeth, played by Dawson — a hypnotherapist with the apparent ability to not only see into Simon's mind but to completely control it.

These rapid direction changes are disorienting but one suspects that is entirely intentional. In a film in which motivations are revealed in increments, it helps to have the audience as misdirected as the characters. Boyle says that even the artwork at the centre of the criminals' plot is a part of this tactic. Witches in the Air by Goya "introduces a slightly surreal element into the film to prepare you".

Depending on your viewpoint, the use of hypnotherapy as the plot's driving force might add to this sense of the surreal. In a film more bound up in realism, it would be laughable to posit the possibility of mind control through hypnotherapy, but it's easier to swallow in the hypercolour confusion of Trance.

The film's actors are split on this issue. Dawson says she had a very intense experience in a hypnosis centre in California which convinced her that "it's not a parlour trick or a gimmick." It didn't work on McAvoy, but he still believes "it has a place and a power, even if that power is placebo. Placebo is a powerful drug for some people."

Cassel's response is the most revealing. While he was resistant to being hypnotised, he thinks he knows why the subject fascinates his director. "Danny Boyle is a control freak. Maybe he wanted to talk about that. It's a personal problem for him and that's what makes it so interesting."

Control freak he may be, but he's a prolific one. Boyle managed to pull off two completely different projects concurrent with the production of Trance: directing the 2011 theatrical production of Frankenstein and acting as artistic director for the Opening Ceremony of the 2012 Olympic Games. The pressure on an Olympic opening ceremony is huge, with each country attempting to top the last. But when Boyle is asked if he felt that pressure he hesitates slightly before responding.

"Well ... no, to be honest. People say were you nervous on the night, and I wasn't nervous at all." The relaxed attitude extends to his advice for the next opening ceremony, to be held in Rio De Janeiro in 2016. "I think Brazil has such personality. Provided they just reflect that personality, they'll be fine."

With all this so recently behind him, one might expect Boyle to take a break. But this doesn't seem to be in his nature. He's currently working on two period films — another new genre for him — and is keen to develop an original musical. Excitingly for fans, there are also preliminary plans for a sequel to his 1996 hit, Trainspotting, about drug culture in Edinburgh. He confirms that "We're trying to make a Trainspotting 2 — T2," adding that he doesn't know what James Cameron will think of that title.

The variety of work Boyle produces makes it tempting to try to tie down Trance, to figure out where it fits in his ever expanding portfolio. But Cassel feels this would be a mistake. "Any genre movie made by a good director becomes that director's movie and nothing else. It's a Danny Boyle movie."

And as his other leading man, McAvoy, reminds us: "He's not making obscure art. He's making proper entertainment." On that front, the deliriously paced, lushly shot and brilliantly acted Trance certainly delivers.

Trance is in cinemas across Australia from April 4. Read our review here.
