The much awaited Hong Kong movie Triangle has finally hit our shores. It's an interesting project, given that 3 HK directors - Tsui Hark, Ringo Lam and Johnnie To - are combining forces to tell a story in the "exquisite corpse" style, where each one takes over from where the other left off, each injecting their own narrative style and spin to the characters and story. It's friendly one-upmanship between the directors in their bout to demonstrate their innovativeness, spontaneity and resourcefulness, but what comes through is clearly a mixed bag, expectedly so since you have three distinct creative inputs.

Does it come across as confusing? You bet, at least for the first third when Tsui creates the characters and the premise. I thought Tsui had tried to bite off more than he can chew. Then again, being the one off the starting blocks, he might be trying to provide as many possibilities and directions that the narrative can choose to adopt and examine in depth or drop altogether. And he doesn't get involved in the chewing anyway, as that's left to Ringo Lam to digest, and Johnnie To to wrap up. Tsui creates a trio who are hard pressed for cash. In Mok's (Chinese actor Sun Hong Lei) antique shop, Fai (Louis Koo) proposes to Sam (Simon Yam) about a heist, which requires them to utilize the latter's driving skills. A stranger appears and provides them an ancient coin, and a puzzle on a website which directs them to treasure (which includes lingerie!) underneath a government legislative building.

Simple enough? Yes, until we also get thrown many other subplots, some of which involves the original heist gone awry because of Sam's backing out, Sam's wife Ling (Kelly Lin) having an affair with corrupt cop Wen (Lam Ka Tung), Fai being under Wen's payroll and their plot within a plot in the original heist to bump Sam off, so that the adulterous couple can lead a new life, gangland members screwball involvement in the whole scheme of things, and the list goes on. Ideas get thrown into the mix and tossed about, and you can almost hear Tsui's cheeky snickering at how Lam and To will be able to sieve through the mess.

But fret not, I believe Lam had managed to, given that he closed most of the open threads and decided quite cleverly, to focus on the individual motivations involving a love "Triangle", and examined some of the characters in depth. This created a much needed and deserved pause for your brain to filter through the noise Tsui had caused, and made the narrative henceforth more manageable, and it did have some rather creative scenes of violence. Fans of Ringo Lam will have known of his earlier movie City On Fire, which Quentin Tarantino's Reservoir Dogs was widely acknowledged to be inspired from. And in Lam's third of the movie, he provides a throwback to Reservoir Dogs, coming full circle with a scene within a warehouse, a character in bondage, everyone else coming over for their piece of the action, with music played over a turntable.

So what's left of Johnnie To to do? He cleared the mess, literally. I thought he provided the best possible last arc for what had transpired over the last hour, with shades from the Election movie (the hunt for an artifact) and a very, very complicated setup to Exiled styled Mexican stand-offs, together with themes of brotherhood, loyalty and honour all summed up beautifully. And I thought he just had to throw in Lam Suet for comedic purposes to provide one last, but short, complication to up the ante that he too can make things complex! To does what To does best, and by the time the credits roll, you'll be pondering over what had transpired, and no doubt, I believe the talking point will be its ending.

All in all, Triangle proved to be an enjoyable ride. Just endure the messy start to get to the meat, before lasting the final sprint to the finishing line where you'll get that rewarding yarn. I'm not sure if the three directors will collaborate again, maybe they should, but this time to rearrange the order for a different film, and if they're at it, why not make it a trilogy to complete the loop so that everyone has a chance to begin, sustain, and close.

A novel idea, originating in Tsui Hark I believe, to make a film based on the old game of incremental story-telling, passing the baton between 3 of Hong Kong's (once) top directors (they should have swapped Johnnie To for John Woo and called it "The Victims of Jean-Claude Van-Damme Rehabilitation Project"). The result is, sadly, almost as incoherent as a nay-sayer might expect it to be.

The first third of the film (Tsui) is kind of scatter-shot, throwing ideas out there for the other directors to pick up on, centred around a heist movie setup with 3 main protagonists (Simon Yam, Louis Koo and Sun Hong-Lei) - setting up a triangle that clearly hints where he really wants the movie to go. This section does suffer from that amphetamine-high lack of focus that sometimes afflicts Tsui Hark when he has too many ideas for a movie, and can't decide which ones are really important.

Ringo Lam takes over just before 30 minutes in, and the mood shifts - he evidently wants to create a psychological horror instead of a crime movie, and shifts the focus more to the characters played by Kelly Lin and Gordon Lam. This part is eerie and oblique, a little surreal at times but much more focused.

Then Johnnie To comes in for the final act, and decides that the film should really be... a farce! Perhaps it's his way of commenting on the baby he has been left holding. Every character that's been introduced so far is brought back into play, along with a couple of new ones (notably Lam Suet), and the plot plays itself out in an elaborate comedy of errors hinged upon a series of entirely implausible coincidences. The finale is a gun battle vaguely reminiscent of those in THE MISSION or EXODUS, but with a more comical coating. It's a bit Shakespearean, but falls short of The Bard's wit.

The shifting of tones, and the diverting focus of the narrative, is exactly the sort of problem you'd expect a movie with three directors and three script-writing teams to have. Perhaps that was the point, and each director deliberately took the movie into their own favourite territory when they took the reins. I guess that's how it usually happens when people play the game amongst themselves (I forget the name of it, never really saw the appeal), but they perhaps failed to factor in that the game is more fun for the people playing it than for somebody who simply gets handed the end result. The production process may be interesting to talk or think about, but probably makes for a less enjoyable film than a more conventional collaboration would have.

I did enjoy Ringo Lam's section though - hopefully it's a sign he's going to be doing more work in Hong Kong again!

Fear not: the juicy premise of putting three masters of HK violent cinema in one movie delivers one of the most entertaining action movies of 2007.

The film is a palpable thrill-ride, with an air of unmistakable cool and sheer brassiness of style. With scarcely time to slow-down, the silly and initially confusing but heavily entertaining and ultimately straightforward plot runs through a hundred twists and turns on its way to the seat-gripping finale that is the last third of the film.

The three segments directed by Tsui Hark, Ringo Lam and Johnny To (apparently in that order, although it was not indicated in the film) are distinct in style and mannerism, but near-seamlessly integrated into a single experience. Not only did they use three directors, they also used multiple script-writers. Do not expect any section-markers here, though: it is not three stories, but one story told in three consecutively more elaborate segments which represent the vision and prowess of one director each - without, however, appearing needlessly patched-together or unfocused. So, to compare this to that other Asian 3-in-1 package, the excellent Three Extremes (with Takashi Miike, Fruit Chan and Park Chan-Wook), is to miss the point. Here we are dealing with a unitary experience, one not divisible by three.

Fans of each director will find much to comment on the stylistic differences between each section. Best known perhaps for his kung-fu productions (at least in the West), the multi-talented Tsui Hark delivers a cool, crafty ambiance in his piece. Ringo Lam, a long-line police action-drama director, likewise carries the torch with a surprisingly mellow and tactful show-of-hands. It is really the last segment of the film, under the steady hand of the miracle-worker Johnny To - the brilliant director of gems such as Election I & II and Exiled - that really puts this work in the category of must-see cinema. It would be impossible to describe just what makes the last act so good without giving something away, but suffice to say the success lies in its mixture of suspense, action and black humour in a dazzling tour-de-force. And yet, To's section makes sense only in the context of the whole; it would not be possible to appreciate the finale without going through the first and second acts. The third act is the charm, but only because the first two acts lead to it and suggest it with force and clarity. By its combination of three geniuses, the impeccable thrill of the film gets multiplied by three, making the end result something greater than the sum of its parts.

The actors are adequate and the chemistry between them works well. This is not an especially 'deep' thinking-man's movie by any stretch - character-development especially is among the real weaknesses of this movie - but for what it's worth, the characters deliver their lines and express their emotional range quite convincingly (with a few notable exceptions). The fraternal chemistry between the main characters saves much of the hapless script. But really, this film is about action, violence, crime, morality and love - the stuff of entertainment. Maybe not serious or tight enough for some, the over-the-top story proves highly entertaining as a backdrop for the stylish visual work emanating from the three great directors.

I'm willing to forgive this movie its obvious shortcomings: its unexplained plot-ends and side-tracks, its focus on action and shine over drama and substance, its use of three writers in the seemingly impossible task of writing a single storyline. Bottomline: It works! Sometimes heckling about details seems petty when what is iffy in ideation is saved in execution. Minor script is turned into a major movie.

Absolute entertainment, with a touch - or two, or three - of genius.
