Season 3

With this season of Heroes adding new villains to the show, this episode goes into the creation and design of the Level 5 containment facility that has been built to house them as they are captured. Writers and producers are also interviewed about how they manage to come up with a shocking cliffhanger at the end of each episode. Included is backstage footage of Jack Coleman (HRG), Kristen Bell(Elle), and Santiago Cabrera (Isaac Mendez).

This episode explores how the technical crew is pushing the limits of current technology to pack effects worthy of a feature film into a weekly TV show. In particular, it goes behind the scenes of how the bank raid scene was filmed.

This episode explores the quasi-religious themes that are developing in Heroes, as the audience finally starts to find out where the various heroes and villains are getting their amazing powers from. Interviewed are Malcolm McDowell (Linderman), Cristine Rose (Angela Petrelli), Masi Oka (Hiro Nakamura) and executive producers Tim Kring and Mark Cossey.

Interviewed are Cristine Rose (Angela Petrelli), Adrian Pasdar (Nathan Petrelli), Milo Ventimiglia (Peter Petrelli) and Jack Coleman (HRG).

Heroes Unmasked takes a further look into the trials and tribulations of troubled teen, Claire. Having come face to face with Sylar in episode one, she also has an absent dad and two mums to deal with. With Claire and her family in greater danger than ever before at the creepy hands of puppet master Eric Doyle, Unmasked pulls the strings of all the leading cast to see how they created scenes with such tension and fear. And through speaking to the show's producers and writers, Unmasked reveals how those sinister scenes with Sylar borrow from the greatest traditions of teenage horror movies to show how life for Claire Bennet will never be the same again.

Whether creating the future or the revisiting the past, building a set or adapting a location, designing Heroes is both vast and varied. With Haiti taking centre stage in Heroes this week, Heroes Unmasked steps back in time to look at how Production Designer Ruth Ammon and her team planned out their design from the very beginning. The cameras then jump forward to see how these designs were translated onto set, bringing the flavour of Haiti to the locations of Los Angeles.

The soundtrack to Heroes has been as distinctive and diverse as the Heroes themselves, and this week Heroes Unmasked joins composers Wendy Melvoin and Lisa Coleman at their studios in Los Angeles to hear how their musical magic is created. Having once been part of Prince's Revolution, Wendy and Lisa have become highly regarded composers and performers in their own right, and from day one on Heroes they have engineered a sound that is that is both epic and ethereal.
