Heroes star Masi Oka confirmed that his character Hiro's sudden landing in fuedal-era Japan in last season's finale will be a major story arc for the series, lasting 7 or 8 episodes. Classic Star Trek actor George Takei will return as Hiro's dad, and even though they have already filmed three episodes of the show, Oka couldn't say when or exactly how the father character will appear. Since Heroes took off, fueled by reaction to his comic fanboy-turned-supergeek character, Oka described a jet-setting lifestyle including a major part in Steve Carell's upcoming Get Smart remake and publicity trips to Monte Carlo. "Words can't describe the change that's happened in my life," he said, refusing to speculate on the show's chances for snagging an Emmy nomination when the announcement comes Thursday, perhaps for fear of jinxing it all. "We've won the lottery and we're living the dream."
