The 1979 production of Tinker, Tailor, Soldier, Spy is great on dvd

The grainy picture adds to the authenticity

I have recently praised several blu-ray editions of classic films and television series. The blu-ray technology in most cases enormously enhances both the visual and the audio enjoyment. However, there is at least one television series, the 1979 BBC version of John le Carrés Tinker, Tailor, Soldier, Spy, in which the old dvd format, with its grainy picture, actually adds to the impression of authenticity.

Sir Alec Guinness as George Smiley

There is a new movie version of le Carrés novel, which is said to be good too, but it is difficult to imagine that it could beat the "original" with Sir Alec Guiness in the main role as George Smiley.
Also the other actors are outstanding, as is the music and camera work. This was British television at its best!
