In 2002, when Will Smith was still filming "Men in Black 2" with director Barry Sonnenfeld, Sonnenfeld was discussing the plot of "Men in Black 3" with Smith. At that time, Sonanfeld hoped that the third episode of the film would have a story of traversal. J went back to the past and found K's secret while saving K. But such a simple idea that is not technically difficult to realize has dragged on for ten years to become a reality.
On April Fool's Day in 2009, Sony announced the filming plan for this film and also asked the screenwriter to write the script. At that time, neither Will Smith nor Tommy Lee Jones decided to return to the crew and play the role that has been around for more than ten years again. At the same time, the writing process of the film's script was not smooth, and a story that traverses is not easy to "make up". Adding the weird humor and weird plot in the previous two movies, it is not easy to maintain a high degree of consistency in style. So, on the basis of the script written by Ethan Cohen, Sony recruited David Cap to revise the script.
The bidding for nearly ten years has consumed a lot of energy from Sonamfeld. Moreover, in the past ten years, various superheroes and various sci-fi blockbusters have grown on the screen.
