Bizarrely the English title of the film is Conspirators, which while hinting at some kind of crime-fighting partnership between Cheung and Kwok, it does unnecessarily disassociate itself from the previous two films. In Chinese the films were called "C grade Detective" and "B grade Detective" respectively, and this pattern appears to be continuing to some degree, with an "A" motif in the Chinese title, though the second character also appears to be different to those in previous installments.
Other than that, however, the trailer seems to promise all the same dubious thrills the Pangs have become famous for over the years - sepia toned cinematography, loud, shouty performances and dodgy CG effects work. Here's hoping that Conspirators can also deliver in the cop thriller stakes.
