Agent J travels in time to M.I.B.'s early days in 1969 to stop an alien from assassinating his friend Agent K and changing history.
Agent K being 29 in 1969 implies that he was born in 1940 (or late in 1939). Either way, this makes the character of K older than Tommy Lee Jones himself, who was born in 1946.
Prison Guard #1:
Well, well, Boris the Animal has a visitor. I guess one every 40 years is okay.
When J is driving to Coney Island and is stopped by the two police officers, the view of Coney Island in the background is wrong. You see the Wonder Wheel Ferris wheel and to the right you see the Cyclone roller coaster. The only way you could see the Cyclone to the right of the Ferris wheel would be if you were on the boardwalk, on the beach, or in the Atlantic Ocean. (The tall cylindrical ride between the coaster and wheel is verification that the roller coaster shown is the Cyclone.) In addition, in 1969 there were two other roller coasters - one of of which would've been seen in that view - the Tornado which would be to the right of the Ferris wheel which means the proper view should be two roller coasters with the Ferris wheel between them.
This is the first film in the series not to have an opening credits sequence.
The Chinese restaurant scene has been censored for the mainland China release. The sequence with J and K in the back room has been edited to remove all shots of Wu, thus eliminating the revelation that Wu is actually an alien. A subsequent moment with J neuralyzing a group of ethnically Asian bystanders has also been deleted.
