I hired this from our library, and was agog. I saw the latter half of Tinker in 1980 when it was televised and always wished I had seen the whole thing. Now that I am older, I have developed a real interest in espionage, and consequently, rented the video set. The cast list is simply unbelieveable. The BBC could at that time, get so many big names together to do a major series, see for example "I Claudius". Sadly, the BBC today is a shadow of its former glory, and we in the UK have to either watch the old shows and dream, or watch the BBC in the present and be so disillusioned. I prefer the former. I can't pick out any performance in particular, because everyone was marvelous. Ian Richardson, who I have always admired, from seeing him as Neuheim in "Private Schulz", is possibly the very best, if I *have* to choose. If you are in any way interested in spying, or just love a really good intelligent thriller, this is for you.
