First Man 4k tells the story of two US astronauts who visited the moon in 1969. Special attention is paid to the life of the more famous Neil Armstrong, who has a cult phrase about his own first step on the lunar surface. This famous step was preceded by years of hard training, dangerous situations during preparation and difficult moments during the mission. There were also several explosions and constant doubts about the success of this project. To be the first on the moon, he had to leave his two sons and wife at home. When he returned from outer space, the main character confessed that the most difficult for him were the fears that he would not be able to return to Earth. But despite this risk, the man decided to go on this space flight. In 2012, this legendary astronaut died, but the memory of him will live forever in the hearts of millions Americans. Armstrong has been recognized as the greatest hero of all Americans who have ever lived. To achieve this prestigious title, Neil had to pass many hardships, most of which are demonstrated extensively in this film.
