Garbo the Spy (documentary film)

For any fan of espionage, or the art of counter-intelligence, this is an amazing DVD. B-) The film is wonderful ... the ending will make a bit more sense if you watch one of the extras, an extended portion of Nigel West's interview in which he talks about how he found the man codenamed "Garbo," and brought him to the UK in 1984 for honors and reunions (technically, mild spoiler about finding the man, but not egregious).

Really worth finding at your library, or online video rental service.
