Nowhere near as bad as you might expect. In fact, quite entertaining. Bearing in mind it was made in 1961, the special effects (e.g. of a dried up Thames and a London shrouded in mist) are quite good. However, the premise remains a bit silly. Janet Munro had a nice arse.
Probably Val Guest's finest film and also probably one of the finest sci-fi films the UK has ever produced. Thoughtful rather than paranoid, and tense rather than panicky, it offers a delightfully British spin on the 'nuclear bombs have knackered the world' sub-genre. If possible, track down the BFI restoration as it's a beautiful piece of work on a splendid film.
This little end times flick fully charmed me. Something about the spit fire dialogue, and down right britishness of the affair won me over. Granted the plot is straight out of Cold War paranoia but the ultimate effect I felt was quite effective. The characters were quite likable and I found myself swallowed up in this tale of world destruction.
Excellent tension with this story. first class script and solid acting. Leo McKern gives such a good performance. watch out for the appearance of Maurice Micklewhite (soon to be Michael Caine) as the policeman in the fog.
