The Buddy Cops:
Gruff veteran of the extraterrestrial police force, Agent K (Tommy Lee Jones) recruits quick-witted whippersnapper Agent J (Will Smith) to give him someone to grumble at.
J’s first experience with the Neuralizer, an eraser wand that enables MIB agents to wipe then rewrite people’s memories.
Agent K provides one woman with a rather lacklustre backstory (“Beatrice, there was no alien. The flash of light you saw in the sky was not a UFO. Swamp gas from a weather balloon was trapped in a thermal pocket and reflected the light from Venus”) so Agent J gets her groove back, re-writing her romantic foibles; “And now that he's gone you're gonna go into town, you go to Bloomingdale's and find some nice dresses, get yourself some shoes, you know, find somewhere, maybe you can get a facial. And, uh, oh - hire a decorator to come in here quick, 'cause... DAMN.“
