The DVDs, of course, are PAL and mostly Region 2, so if you're not in Europe, you'd also have to be sure that you have the capabilities to play them. (Most people with a DVD drive on their computer and some free software do these days.)
Among the many other spy-related bargains are:
The Rivals of Sherlock Holmes, featuring some great Victorian espionage as well as terrific Holmsian mysteries (Review here)
Finally, the company have also made available some of their wonderful documentaries from these ITC Complete Series sets as standalone discs. This is very handy for international viewers who might own, say, The Saint in its entirety from A&E or Umbrella, but still crave the excellent feature-length making of, The Saint Steps In... To Television (review here). Also available is the equally wonderful Prisoner documentary, Don't Knock Yourself Out (now also available on A&E's American Blu-ray release of the series) and In Character: Richard Bradford from Network's Man In A Suitcase complete series.
So UK readers, let the bargain-hunting commence! But hurry, because the sale ends tomorrow, January 16! And for everyone else, it really doesn't hurt to have a yearly Buyer's Guide to Network's spy products. They are many and they come fast and furious. Already scheduled for 2010, we have Danger Man: The Complete Series 1 and the long-awaited Callan: The Monochrome Years. Network is probably the most consistant company in the world for quality spy TV releases, and that tradition looks to continue.
