Details about the plot official are limited, but Men in Black International is expected to present a new cast of characters existing in the same universe. The original film will be centred on London, but will also feature action in other parts of the world. Neeson is rumored to have played the head of the U.K. branch of the foreign Investigation Agency, similar to the role played by Rip Torn as part of the U.S. Agency featured in previous films.
The only character to return will be agent one, the head of the American branch of the organization Men In Black, which was portrayed by Emma Thompson at Men In Black III. Thompson will reprise her role in some form , offering some continuity between the previous trilogy and the new film.
