This is a review of the blu-ray edition on sale in the UK.
The transfer is for the most part, excellent. There are some moments where there appears to be a bit of layer damage that contributes to a very red tinge for a few seconds only, but this is nothing like as prevalent as suggested by another reviewer, and certainly not serious enough to spoil anyone's enjoyment. The sound is excellent, and particularly showcases Alex North's justly celebrated music. As for the "softness" - all I could see was that in what I think was a somewhat outdated technique even in 1960, shots of Jean Simmons seem to have been done in soft focus, which then contrasts very sharply with other shots of the scene. But generally, the film is sharp and clear.
As for the film itself, it has some terrific performances. Charles Laughton's manipulative senator is a particular highlight. I had also not realised quite how sensitive an actor "tough guy" Kirk Douglas was. But the film is stolen by Peter Ustinov, whose Oscar was justly deserved.
Many of the techniques used are obviously dated when viewed against more recent films. Accept the film in its own era, however, and this remains one of the benchmarks for telling an epic story. Stanley Kubrick had his own reasons to disown the film, but he could just as well have been proud of it.
