NBC has taken its Heroes Reborn gag impressively far with the crafting of an actual trailer shown at the upfronts (though one that curiously never surfaced online), and now another returning cast member has pledged to the elaborate joke. Prior series star Greg Grunberg will turn his head and squint through NBC’s Heroes Reborn revival, at least until the network decides its ridiculous prank has gone far enough.

Entertainment Weekly reports that Grunberg will reprise his role as psychic police offer Matt Parkman for a guest arc in the new 13-episode series, joining fellow alum Jack Coleman (Noah Bennet), Masi Oka (Hiro Nakamura) and Jimmy-Jean Louis (The Haitian). No word on what the arc would entail exactly, but Grunberg previously told the outlet “It’d be great to use that cop character as an investigative tool to find new people with power.”

So reads the official Heroes Reborn logline:

From original creator Tim Kring, the supernatural phenomenon begins again with a fresh crop of inspiring heroes who take on the ultimate struggle between those with extraordinary abilities and those with nefarious motives to hunt and harness their powers. Epic adventures await these newly empowered allies as they cross paths with some of the original characters (such as the beloved “HRG” and fan-favorite time-traveler Hiro Nakamura), unlocking the mysterious fate of the universe and their place within it.

In addition to Chuck / Thor: the Dark World star Zachary Levi, Heroes Reborn boasts among its cast Once Upon A Time villain Robbie Kay, Ryan Guzman, Danika Yarosh, Judith Shekoni, Kiki Sukezane, Henry Zebrowski and Gatlin Green. Past series leads Zachary Quinto, Ali Larter and Milo Ventimiglia all previously shot down the possibility of returning to the Heroes franchise, along with Nashville star and Heroes alum Hayden Panettiere.

Continue the Heroes Reborn gag with its first teaser below, and see when NBC finally breaks in advance of its fall “premiere” on Thursdays at 8:00 P.M.!
