''The Watch'' is a 2012 comedy movie about a Neighborhood Watch that discovers an AlienInvasion. It was directed by Music/TheLonelyIsland member Akiva Schaffer and written by Creator/SethRogen and Evan Goldberg.

Originally titled ''Neighborhood Watch'', it was retitled and the marketing was changed to focus on the aliens after [[http://en.wikipedia.org/wiki/Shooting_of_Trayvon_Martin an incident in Florida where a Neighborhood Watchman shot a teenager dead]].

The story takes place in the small town of Glenview, Ohio. It begins when Evan Trautwig (Creator/BenStiller) forms the Watch after the night watchmen at the place he works is killed and the police don't seem to care. He's joined by three others: Bob (Creator/VinceVaughn), a construction worker with a rebellious daughter, Franklin (Creator/JonahHill), a high school dropout who wanted to be a policeman but failed all the necessary tests, and Jamarcus ([[Series/TheITCrowd Richard]] [[Series/GarthMarenghisDarkplace Ayoade]]), a recent divorcee. None of them are as dedicated as Evan, though.

Then they quite literally crash into the aliens' plot. The aliens are replacing people in the town as part of their preparation for a full invasion of Earth. Now its up to them to find out who has been replaced and stop them in time.

!!Tropes in ''The Watch'':
