So is "Prometheus" the prequel to the 1979 movie "Alien" by the same Director Ridley Scott? I think so.
Starring Noomi Rapace, the original actress in the movie "The Girl with the Dragon Tattoo", Michael Fassbender of "X-Men First Class" fame, Guy Pearce, Logan Marshall-Green and Charlize Theron, who was most recently seen in "Snow White and the Huntsman", it was a controversial movie that explored the origin of man and appeared to bridge the missing links to the alien movie. I feel a movie is just a movie and should not be taken too seriously since it is usually made more for entertainment than anything else.
At the start, it probably showed how mankind was created from the DNA of a humanoid alien. Fast forward to a futuristic 2089 when archaeological digs at various continents unearthed similar star maps pointing to a series of planets. Four years later in 2093, a team of 17 members on board a spaceship were gathered together to explore a distant planet which points to the origin of everything. The expedition was fraught with lots of unknown e.g. row of gigantic structures in a clearing, cylinders with a black oozing substance, decapitated alien corpse, as two crew members succumbed to violent deaths inflicted on them by the alien beings. They referred to the aliens as engineers because of their supposed creation of mankind.
The movie was kind of slow at first as the team was formed and picked up pace about one hour into it. Noomi was the lead protagonist Dr Elizabeth Shaw and her foetal abortion by caesarian was actually quite gross. Michael as the android was cold, calculated and brilliantly mechanical in his movements. I was disappointed with the role that Charlize played because it was sadly insignificant. She is so talented and her acting ability was all wasted here.
Subsequently, a surviving alien was revived by the team and it turned on them, killing most of the members. The remaining survivors discovered that the aliens were bent on destroying their creation and despatched their spaceship to go to Earth to decimate the human race. To prevent the impending war, some of them sacrificed their lives to prevent the alien spaceship from taking off into the sky.
Of course in the end, the brutal engineer was killed but In the process, a new alien form, similar to the one in the "alien" movies was created. The only survivor, on board the Prometheus, Dr Elizabeth Shaw recorded a message log as she escaped from the planet in one of the alien's spaceship. In fact, this message sounded familiar as if I have heard it before in one of the alien movies. That is probably the connection between this latest movie and the earlier ones.
