We've reported a couple of times here about an intriguing-sounding, unnamed collaboration between Hong Kong superstars Johnnie To, Tsui Hark and Ringo Lam. Referred to as a "puzzle film," the movie is expected to be a 90 minute crime feature, with 30 minutes directed by each man, based on what has occurred in the previous section (there is not a screenplay for the film; each bit is being made independently, according to the desires and ideas of its director).

A couple of weeks ago it was revealed to the surprised of no one that To's long-time collaborator Simon Yam would star in his segment, and now further details about the film are starting to leak out. Though no cast members apart from Yam have been confirmed, it's expected that Louis Koo, Kelly Lin and Sun Honglei will also star in one or more segment. In addition, the film -- currently called Triangle -- now has a vague plotline from which Hark, who is at the helm of the first segment, will work. According to people at Twitch who can read the Chinese media, the film will start with "a few guys with little money and a lot to worry about [who] gather together to chat about how to get rich. Then a mysterious man sitting in the same room approaches them with a treasure map. ... To get their hand on the treasure, the map is only the first of a series puzzles they have to solve."

Frustratingly, there's still no reliable info available about shooting or release dates. Rest assured, however, that whether you like it or not, we'll let you know when those details emerge.
