In 1973 a nuclear-powered spaceship is perched on the cratered surface of Mars, sent to rescue the crew of a previous, ill-fated mission. The sole survivor of that crashed ship, Col. Edward Carruthers (Marshall Thompson), is suspected of having murdered the other nine members of his crew for their food and water rations, on the premise that he had no way of knowing if or when an Earth rescue mission would ever arrive. Carruthers denies the allegation, attributing his crew's deaths to a hostile alien life form encountered on Mars.
In early 1950s southern California, Dr. Clayton Forrester (Gene Barry), a scientist who had worked on the Manhattan Project, is fishing with colleagues when a large object crashes near the town of Linda Rosa. At the impact site, he meets Sylvia Van Buren (Ann Robinson) and her uncle, Pastor Matthew Collins (Lewis Martin). Van Buren was told that the meteorite came down at a low angle, while Forrester observes it appears far lighter than normal for its massive size. His Geiger counter also detects it is slightly radioactive, but the object is still too hot to examine closely. Unable to account for these anomalies, Forrester is intrigued and decides to wait in town overnight for the object to cool down.
The narrator (Morgan Freeman) explains how humans were unaware that intelligent extraterrestrials were making plans to occupy Earth. Ray Ferrier (Tom Cruise) is a divorced crane operator longshoreman who works at a dock in Bayonne, NJ. Ray is estranged from his children. His former wife, Mary Ann (Miranda Otto), later drops off the children, 10-year-old daughter Rachel (Dakota Fanning) and teenage son Robbie (Justin Chatwin), at Ray's house in Bayonne on her way to visit her parents in Boston. Unexplained changes in the weather occur, emitting lightning that strikes multiple times in the middle of an intersection and disrupting all electrical technology in the area.
The early part of the film follows the experience of a late 19th-century journalist from Woking, known as "the writer", involved with the landing of a Martian invasion spacecraft. When the crashed cylinder opens, the Martians start killing anything that moves with a "heat ray" weapon. The writer discovers his house is in range of their heat ray and decides to rush his wife and servant to her cousins' home in Leatherhead; once there, he returns in order to return the borrowed cart to its owner, unaware that the invading Martians are now on the move.
Nyah, a female alien commander from Mars, dressed in shiny black vinyl, heads for London in her flying saucer. She is part of the advanced alien team that is looking for Earth men to replace the dying male population on her world. Because of damage to her saucer, caused by entering Earth's atmosphere and then colliding with an aircraft, she is forced to land her damaged flying saucer in the remote Scottish moors, near a local village. She is armed with a raygun that can paralyze or kill, and she also has a tall, menacing robot named Chani.
Roughly two years after the first film, an American space mission lands on Mars; Patrick Ross, the commander of the mission, collects soil samples. However, the temperature on board the ship thaws a mysterious substance within a sample, which then attempts to infect the astronauts, causing a seven-minute time gap in radio contact between Earth and the shuttle. The mission is still considered a success and the crew safely returns to Earth. Only Dr. Cromwell, a former scientist and now an inmate in an asylum, reacts violently to their return.
An American astronomer obtains images of Mars suggesting large-scale environmental changes are occurring at a pace that can only be accomplished by intelligent beings with advanced technology. At the same time a colleague claims to have been contacting Mars by radio, using technology stolen from the Nazis after World War II. He communicates first through an exchange of mathematical concepts, like the value of pi, and then through answers to specific questions about Martian life. The transmissions claim that Mars is a utopia fueled by nuclear power, which has led to great technological advancement and the elimination of scarcity, but that there is no fear of nuclear war.
The rocketship MR-1 (for "Mars Rocket 1"), returns to Earth after the first manned flight to Mars. At first thought to have been lost in space, the rocket reappears but mission control cannot raise the crew by radio. The ground crew land the rocket successfully by remote control. Two survivors are found aboard: Dr. Iris Ryan (Naura Hayden) and Col. Tom O'Bannion (Gerald Mohr), the latter's arm covered by a strange alien growth. The mission report is recounted by Dr. Ryan as she attempts to find a cure for Col. O'Bannion's arm.
Le film raconte, avec un premier documentaire découpé puis comme une comédie italienne, l'arrivée d'un groupe d'étrangers dans un village de la Vénétie profonde: une enquête des Carabinieri révélera une folie latente répandue dans la population du village qui peu de choses ont à voir avec les extraterrestres.
The film shows the earth from the view of the Martian flying machines which did not land but used cameras to film earth society. It then follows one average (what it believes to be) earthling and its civilization, by in effect showing a "day in the life" and how they live it. First, it shows one going through dinner with a precisely regulated feeding (vehicle refueling from a gas pump), then it must take its rest (pulling into an attached garage next to a house), because it will have a busy day the next day.
The story involves the people of Mars, including Momar ("Mom Martian") and Kimar ("King Martian"). They're worried that their children Girmar ("Girl Martian") and Bomar ("Boy Martian") are watching too much Earth television, most notably station KID-TV's interview with Santa Claus in his workshop at the North Pole. Consulting the ancient 800-year-old Martian sage Chochem (a Yiddish word meaning "genius"), they are advised that the children of Mars are growing distracted due to the society's overly rigid structure; from infancy, all their education is fed into their brains through machines and they are not allowed individuality or freedom of thought.
Une expédition arrive sur Mars et découvre des Martiens pacifistes. La fille du leader martien accepte de les accompagner sur la Terre pour délivrer un message de paix.
John Carter (Antonio Sabato, Jr.) is a modern-day U.S. Army sniper serving in Afghanistan, wounded in the line of duty and used in a teleportation experiment wherein he is transferred to Barsoom, here depicted outside our solar system. On this world, Carter exhibits the ability to leap amazing distances. Initially enslaved and held against his will on a chain and collar by the Tharks, he earns a rank among them and later saves a rival group's princess, the human-looking Dejah Thoris (Traci Lords), from death.
In the 2040s, a Martian research base, Tantalus Base outpost, is created. The eight person crew, who have been stationed there for six months, are only nineteen hours from the completion of their research mission. The spacecraft Aurora is inbound from Earth and will collect the team by lander from a prearranged site. Mars scientist Marko Petrović has found samples that may point to life on the planet. Without revealing his discovery, he devises a ruse for one last sojourn on the surface. Crewmate Richard Harrington drives Petrović in a solar powered rover to the spot where he had found the sample. After he obtains soil with the biological agent present, a fissure swallows Petrović.
Late one night, young David MacLean (Jimmy Hunt) is awakened by a loud thunderstorm. From his bedroom window, he sees a large flying saucer descend and disappear into the sandpit area behind his home. After rushing to tell his parents, his scientist father (Leif Erickson) goes to investigate David's claim. When his father returns much later in the morning, David notices an unusual red puncture along the hairline on the back of his father's neck; his father is now behaving in a cold and hostile manner. David soon begins to realize something is very wrong: one-by-one he notices certain townsfolk are acting in exactly the same way. Through his telescope, David sees child neighbor Kathy Wilson walking in the sandpit, when she suddenly disappears underground. David flees to the police station for help, and he is eventually placed under the protection of health-department physician Dr. Pat Blake (Helena Carter), who slowly begins to believe his crazy story.
