Now that he can’t save the world (or cheerleaders) anymore as time-stopping teleporter Hiro Nakamura in NBC’s now-canceled Heroes, Emmy-nominee Masi Oka is moving into a new prime-time do-gooding role: EW has confirmed reports that the actor has been cast in CBS’ Hawaii Five-0 reboot, which is shaping up to have some serious geek-pop cred. The cast: Alex O’Loughlin (Moonlight), Daniel Dae Kim (Lost) and Grace Park (Battlestar Galactica). The exec producers: Alex Kurtzman and Roberto Orci (Star Trek; Fringe). Just what kind of mystery island drama is this new Hawaii Five-0 going to be, anyway? Oka will reportedly play a coroner in the show’s fourth episode and may become a recurring character in the series.
