Yes great series. Also available on BBC DVD according to a round robin I've had from the BBC Shop.Always remember the episode where one of the PoWs feigned madness but he really became insane and was repatriated.
Amazing isn't it, a cult programme that hasn't been repeated for years (decades!), that hasn't been out on DVD because the Beeb and their US partners (Fox?) couldn't reach an agreement, and they just toss it out on a minority Freeview channel with no fanfare at all.
Was only complaining the other day in anothr thread about it not having been repeated for years (I remember ages ago it was shown on UK Gold, along with Tenko).
Sitting here with my drool bucket waiting for David McCallum, Robert Wagner and Christopher Neame to appear
I live quite close to Ealing Studios and a friend who worked there took me on the set. Incredibly small, and the castle was made of painted polystyrene. Sadly none of the cast were about.
