TV on DVD: Aliens of 'Dark Skies' land

DARK SKIES: DECLASSIFIED COMPLETE SERIES

Series Aliens are here! And they're changing history! Eric Close and Megan Ward were out to stop them in NBC's 1997 period piece, playing '60s agents battling both the invaders and the conspiracy keeping them secret. That involved interacting weekly with real-life people and events: John F. Kennedy's assassination, Beatlemania, civil rights clashes, the Vietnam War.

Extras Creators Bryce Zabel and Brent Friedman talk in depth about their "alternative history" disguised as "fiction," with comments from their stars; plus international pilot, original sales presentation, more. They're often accessed by "secret" menus emulating the show's hush-hush posture, also maintained in eyes-only Zabel essay booklet.

List price $45 for 19 episodes, out today from Shout!
