Activision has signed Christopher Walken, Gary Oldman and Michael Madsen, along with a host of other, lesser stars (notably Michelle Rodriguez of Resident Evil movie fame), to lead the voice cast in True Crime: Streets of LA. God knows how they managed that. The other stars, for the sake of completion, are Russell Wong, Ron Perlman, CCH Pounder, James Hong, Mako and Keone Young.
The Hong Kong action flick/American crime drama-inspired True Crime (Martial Law!) is due out on PS2, Xbox and Cube "in the fall".
