**An excellent sci-fi film.**

This is one of the best and most influential films from the early days of sci-fi. The theme was not new, there were several films about aliens and flying saucers, but this is one of the best and most impactful. The script is simple: the atomic arms race was threatening the world with yet another war and the hypothetical insertion of nuclear weapons into rockets led to an alien species fearing for their own safety, as they had learned to live without weapons and in peace. So, they decided to send a messenger to our planet.

I find it very interesting that the script focuses on the need to maintain peace, hardly acquired (the film is from 1951, six years after the end of the Second World War) and already under threat from growing rivalries. Nuclear weapons were new, but already capable of inspiring fear on both sides and the script fits on top of all this, taking advantage of a trend around aliens and the hypothesis of extraterrestrial life to create a more technologically advanced civilization. and morally, and from which we can learn.

Robert Wise was a director who was growing and asserting himself. Here, he directed the film with great skill, giving us a superb work. He knew how to bring out the best in each actor and intelligently guide his team. Michael Rennie, an unfamous actor who the public would hardly recognize, was extraordinarily credible as the alien and knew how to balance himself between a very human sentimentality and an austere and very firm stance. Patricia Neal also did a very good job, and Billy Gray was an excellent addition to the cast, with a deeply moving likability. Lock Martin was greatly congratulated for his work, and I believe it was difficult to bear the weight of that kind of armor, but I don't think he did anything special: the only thing he does is stand there and take a few steps.

On a technical level, the film stands out for its excellent black and white cinematography: the film is very sharp, it is very well filmed, it has excellent camera work and the lighting is excellent. The sets and costumes help a lot to make everything even more serious and credible. The film has few special effects, but what it does have is quite functional and realistic enough, except for the flying saucer landing: it's quite obvious that it's a prop hanging from a wire, but I didn't care about that. The soundtrack was created by Bernard Hermann and, without being notable, it fulfills its role well.
