The three masters of contemporary Hong Kong cinema – Tsui Hark (Seven Swords; Zu Warriors; Once Upon A Time In China), Ringo Lam (Full Contact; City On Fire) and Johnny To (Mad Detective; PTU) – join forces for the first time ever to apply their directorial skills 'exquisite corpse' style to Triangle, an "inventive, and darkly comic" (at least according to the Mail on Sunday) crime thriller starring Louis Koo (Flashpoint), Simon Yam (SPL; Lara Croft Tomb Raider: The Cradle Of Life), Honglei Sun (Mongol; Seven Swords), Lam Ka Tung (Mad Detective; Infernal Affairs) and Kelly Lin (Mad Detective; Zu Warriors).

In dire financial straits, down-on-their-luck drinking buddies Sam (Simon Yam), Fai (Louis Koo), and Mok (Honglei Sun) have been forced into considering committing a heist on behalf of some local gangsters in order to get their hands on some much needed cash. That all changes, however, when a mysterious old man appears in their local bar one night with a far more appealing 'get rich scheme'. According to his tip-off, an ancient and priceless treasure is buried beneath a high-security government building and all they have to do is slip in and retrieve it.

Their decision to go for the easier and more lucrative prize naturally attracts the attention and considerable ire of their previous potential employers. But that is the least of their latest problems. Unknown to the trio, Sam's wife, Ling (Kelly Lin), is conducting a secret, illicit affair with a corrupt cop, Wen (Lam Ka Tung), who may or may not have connections to the gangsters in question. To complicate matters further, Ling also has her eyes on obtaining the treasure by whatever means necessary. As these various outside elements collude against them achieving their goal, Sam, Fai and Mok realise they have placed themselves in deadly danger and are individually going to have to make a choice between survival, wealth and friendship.

The filmmaking twist as that we don't have three separate stories here but one, with each consecutive third of the movie directed in succession by Hark, Lam and To respectively, resulting in a film of distinctive parts, from Hark's complex, rapid-fire set-up of the caper, through Lam's tense, character-driven mid-section to Johnny To's darkly comic and elaborately choreographed resolution. A unique approach that has had mixed reviews but certainly found its fans, Triangle (Tie saam gok) is certainly a must for Asian action cinema fans.

Triangle will be released on DVD in the UK on 20th October 2008 by Manga Entertainment at the RRP of £17.99. The disc will feature a 2.35:1 anamorphic transfer and Cantonese Dolby 2.0 stereo and Cantonese 5.1 surround soundtracks with optional English subtitles. Extra features are limited to trailers from other Manga releases.
