Now, drawing on unique insight from the original producer, Glen A. Larson, and exclusive interviews with David Eick and Ronald D. Moore – creators of the series’ acclaimed reimagining that was produced by Universal Cable Productions and aired on Syfy for four seasons – Battlestar Galactica Vault offers a complete visual history of the show’s evolution, from 1978’s ‘Saga of a Star World’ to spinoffs Caprica and Blood & Chrome.

Housed in a novelty extendable cover, the history of the series features a treasure trove of behind-thescenes images, there are concept artwork by legendary artist Ralph McQuarrie, annotated scripts and storyboards, candid behind-the-scenes photography, and 10 meticulously reproduced pieces of memorabilia for readers to remove and examine.
