Men in Black 3

Men in Black 3 (stylized as MIB³ in promotional material) is a 2012 American science fiction action comedy film based on the Men in Black comic book series. It is the third installment in the Men in Black film series, a sequel to Men in Black II (2002), and the final installment of the original trilogy. Directed by Barry Sonnenfeld and written by Etan Cohen, the film stars Will Smith, Tommy Lee Jones and Josh Brolin, with Jemaine Clement, Michael Stuhlbarg, and Emma Thompson in supporting roles. In the film, Agent J is required to go back in time to prevent the assassination of his partner Agent K, the fallout of which threatens the safety of Earth.

Development of the sequel began during filming of its predecessor, with its premise suggested by Smith to Sonnenfeld. Despite rumors of a fallout between Smith and Sonnenfeld during the filming of Men in Black II, their returns were confirmed alongside Jones by May 2010. David Koepp and Jeff Nathanson were later hired to perform uncredited rewrites to Cohen's original screenplay and principal photography began that November. Filming was split into two parts, first occurring between November and December 2010, and restarting between April and June 2011, taking place primarily in New York City. Composer Danny Elfman, who scored the previous two installments, returned to score the third. With a production budget of $215 million, it is one of the most expensive films ever made.
