There a million reviewers out there who can do more justice to reviewing the film itself than I can, suffice to say that for me it is a superb film, and this is the consensus among most people that see it. I want to use this review to point out what a great Blu-Ray this is. As usual Warner Bros. has upgraded to Blu-Ray with love and attention to detail. First of all the picture quality: it's sharp, and the colours are vivid, but it hasn't been over processed to within an inch of its life, and a bit of realistic grain is still present. The film really pops out at you, and you will be amazed that a film from 1956 can look so good on your home TV. I had seen this before on TV and VHS, but this was like seeing the film for the first time. It really looks gorgeous!
It's worth mentioning the extras as well, as you get a whole second feature film: The Invisible Boy (1957) which also featured Robbie the Robot. While clearly a lower budget production (it is b/w) and not of the same ambitious and thought provoking scale, it is still an interesting addition, and quite a bonus to get a film which is unlikely to get a Blu-Ray release in its own right. This also looks to have been restored as well, although it is not of the same eye-popping quality as the main feature. There is also a 55-minute documentary, Watch the Skies, about the explosion of sci-fi films in the 1950s, as well as an episode and some clips of TV programmes from the era that also featured Robbie the Robot. Deleted scenes and trailers for both films round this off.
A superb Blu-Ray release.
