Logan's Run (1976)

It's 2274, and on the surface, it all seems to be an idyllic society. Living in a city within an enclosed dome, there is little or no work for humans to perform, and inhabitants are free to pursue all of the pleasures of life. There is one catch however: your life is limited and when you reach thirty, it is terminated in a quasi-religious ceremony known as "carrousel". Some, known as "runners", try to escape their fate when the time comes, and it's the job of Sandmen to track them down and kill them. Logan (Michael York) is such a man, and with several years before his own termination date, thinks nothing of the job he does. Soon after meeting a young woman, Jessica-6 (Jenny Agutter), he is ordered to become a runner and infiltrate a community outside the dome known as "Sanctuary" and to destroy it. Pursued by his friend Francis (Richard Jordan), also a Sandman, Logan and Jessica find their way to the outside. There, they discover a beautiful, virtually uninhabited world. Logan realizes that he must return to the dome to tell them what he's found and be set free.

One of the Best Sci-Fi Ever and Absolutely Ahead of Time

In 2274, the survivors of a war live in a great domed city sealed from the outside world and their society provides all possible comfort to them. However there is a catch: when the dwellers reach the age of thirty years old, their life clocks become red, accusing that it is time of renewal and they must participate in a ceremony called Carrousel. The misfits are called runners and they are chased by the police force called Sandmen and terminated. The efficient sandmen Logan 5 (Michael York) and Francis (Richard Jordan) work together and they are best friends. When Logan meets Jessica 6 (Jenny Agutter) in a sexual encounter, she sees that he is a sandman and refuses to have sex with him, claiming that it was a mistake of the circuit. Then Logan terminates a runner and when the computer analyzes the belongings of the victim, it assigns Logan to an undercover mission. His life clock is advanced in four years and he is ordered to take the key and seek the Ankh Sanctuary. He uses Jessica to help him, but he falls in love for her while chased by Francis. Logan questions the system and leaves the domed city with Jessica; in the outer world, they find and old man, changing their perspective of life beyond 30.

"Logan's Run" is one of the best sci-fi ever and absolutely ahead of time. Even in 2009 and after watching this feature at least six times, I still love it. The original and engaging story is supported by magnificent cinematography, scenarios, set decoration, special effects, costumes, make-up and music score. Jenny Agutter is amazing and shows a wonderful chemistry with Michael York. One of the best moments is when they do not know the meaning of "beloved husband" and "beloved wife" since these concepts do not exist in their society. Last but not the least, the name of my daughter was inspired in the character performed by Jenny Agutter. My vote is ten.
