In the world of cult spy and adventure TV, the UK distributor and on-line shop, Network, is the oasis that fans have been looking for all their lives. Similar to A&E in the States, Network has been consistently releasing box sets of television series, but they often push their productions further to include high-quality transfers- and to go the extra distance by making available many sets of rare music cues and soundtrack collections. Network pays great attention to details and often includes cool bonus features (even for the music sets). I like to think of them as the Criterion Collection of cult TV.
Spy Vibers have heard about many Network releases over the last year or so, and we even had a give-away contest for Network's soundtrack box set of The Prisoner a while back. Network is currently running a 30% off sale until December 21st on their web-exclusive products. You'll find many DVD box sets (region 2), including their recent release of the rare show, Corridor People (Spy Vibe coverage of the DVD release here and articles about the surreal/satire boom in 1960s England here and here), as well as classics and rarities like The Saint, The Sentimental Agent, Interpol Calling, and Space Patrol. If you can play UK Blu-ray discs, you'll also find Gerry Anderson's Fireball XL5 and Space 1999 (season one of Space 1999 is out this month on region 1 Blu-ray from A&E).
Network has an amazing list of soundtrack sets on sale (look through their website beyond the sale page), including The Prisoner, Danger Man, Man in a Suitcase, The Champions, Department S, Jason King, and the excellent compilation, Music of ITC. There is a lot to explore and discover. Details here at Network. You can also find reviews of Network releases on my fellow COBRAS site, Double O Section.
