Gear up for the upcoming third season premiere of NBC's HEROES with Blu-ray releases of the first two seasons, plus the Collector's Edition of NIGHTMARE BEFORE CHRISTMAS, a new LITTLE MERMAID adventure and more, all on DVD and Blu-ray today.

HEROES: Season Two On DVD And Blu-ray

Rejoin the epic phenomenon as HEROES: Season Two arrives on DVD and Blu-ray from Universal Studios Home Ent.; vfx from Stargate Digital.

Watch the Emmy-nominated show and experience all the new and exciting twists of the astonishing series in this four-disc set that includes every gripping season two episode. Plus, see what could have been with exclusive bonus features that reveal the untold stories that never aired and an alternate ending to the season finale where the fate of humanity takes an ominous turn.

Replacing first-season Supervisor Mark Kolpack is his Stargate Digital colleague Eric Grenaudier, who is no stranger to the show having worked as a compositor on its first season. "Obviously having already spent a year with HEROES, you learn some subtle things like the styles the producers are looking for and the type of effects that seem to be working well for them and for the audience, so you build on this," he said.

Grenaudier adds that Stargate has worked on upgrading the show's obvious effects as well as its more subtle ones. "We've improved simple things like how to light a really big greenscreen, what tweaks we could do to the matte painting later," he explained.

Season three of HEROES will debut with a three-hour premiere September 22 on NBC.
