''Note: This is about the 1953 adaptation. For the 2005 one, see'' '''Film/WarOfTheWorlds'''''.''

The first of several film adaptations of H.G. Wells' seminal alien invasion novel, directed by Byron Haskin and produced by George Pal. It stars Gene Barry as the scientist Dr. Clayton Forrester and Ann Robinson as Sylvia Van Buren, as they must survive a full-scale invasion of Earth by Martian forces.

The film is a PragmaticAdaptation of the novel, taking only the premise and ending with little else from the source material. Nonetheless in an age of alien invasion films such as ''Film/EarthVsTheFlyingSaucers'', ''Invaders From Mars'' and ''Film/TheThingFromAnotherWorld'' this film is regarded as one of the best of that category.

Many years later the film would get a sequel in the form of a [[Series/TheWarOfTheWorlds television series]]. Due to [[HistoryMarchesOn history marching on]] the series {{RetCon}}ned several aspects from the original film, namely the aliens coming from the planet Mor-Tax instead of Mars. Elements of the film would also inspire future science-fiction media, such as ''Series/MysteryScienceTheater3000'', ''WesternAnimation/TheIronGiant'' and ''Film/IndependenceDay''.

!!This film contains examples of:

* ChekhovsGun: When Dr. Forrester brings a Martian probe with blood samples to a group of scientists, they see that the blood is highly anemic. This foreshadows how they were eventually killed by terrestrial bacteria.
* DarkestHour: The film's final act. It's probably among the darkest and bleakest atmospheres put into a 50's alien invasion film; there's absolutely nothing left to hold on to and the protagonist's last remaining goal is to spend the next few minutes of his life with his loved one.
* MoneyIsNotPower: As Los Angeles is being evacuated, people are rioting in the streets. One guy tries to buy his way onto a truck, only to be thrown off while being told "Money's no good anymore!"
* PragmaticAdaptation: The original novel took place in late 1800's England and the aliens piloted towering tripod walkers. This film takes place in 1950's California, and the aliens pilot hovering manta-ray/scorpion spacecraft.
** Originally the spacecrafts were meant to be tripods, but since a tripod effect was difficult to achieve the film instead states that the spacecraft hover via invisible tripod "stilts". In a few shots you can see vague outlines of the "stilts" along with sparks on the ground.
* ReligionIsWrong: Averted in a strange way. The source material (at least the second half) is a firm criticism of religion, and there are religious characters who eventually turn out unhinged and dangerous in the wake of the invasion. The film is almost the complete opposite - the main religious character is kind and righteous and is given a meaningful death, and the closing narration comments on how the smallest creatures of God's kingdom defeated the invaders.
* ScienceMarchesOn: The movie opens with [[VisualEffectsOfAwesome impressive Chesley Bonestelle paintings]] of the other planets of the Solar System ''except'' for Venus. In 1953, the nature of what lay beneath that world's clouds was unknown deserts, swamps, and global seas of carbonated water or petroleum were all considered possibilities.
** Ironically, the grossly inaccurate description of Jupiter is far more telling of Venus' surface conditions.
* TechnologyMarchesOn: Back in the source novel the alien war machines were vulnerable to artillery fire and a torpedo ram, which were the most powerful weapons available at the time. In this film the aliens can survive an atom bomb blast, because otherwise they would be defeated very quickly.
** Reportedly, George Pal asked a Pentagon representative how contemporary armed forces would do against the Martians from the novel. He replied in no uncertain terms it would be a CurbStompBattle for humanity.
