AceShowbiz - Emma Thompson is still the boss in "Men in Black". The British actress is set to return for the fourth installment of the sci-fi film franchise, reprising her role as Agent O, the chief of the Men in Black organization, according to The Hollywood Reporter.

The Oscar and BAFTA Award-winning actress joins Chris Hemsworth and Tessa Thompson who are tapped as the new leads in the upcoming spin-off. Details of Hemsworth and Thompson's roles are currently unknown, but they are expected to play characters similar to Will Smith and Tommy Lee Jones' in the original movie.

The untitled Men in Black spin-off is set in the same universe as the original trilogy. The story will reportedly "see Tessa Thompson's Em try to prove herself by joining the London MIB and will be paired with Chris Hemworth's Agent H. The pair will become involved in a murder mystery that will lead to them on a global journey."

Liam Neeson also joins the cast, reportedly to play the head of the Men in Black organization in London. Kumail Nanjiani and Rafe Spall also join the cast, with star street-dancing duo Les Twins which consist of Laurent Nicolas Bourgeois and Larry Nicolas Bourgeois reportedly to appear in the movie.

"The Fate of the Furious" filmmaker F. Gary Gray is tapped to serve as director, with Matt Holloway and Art Marcum providing the script. Filming has begun earlier this month in London, as Hemsworth was seen on the set for the first time on July 8. The movie is scheduled to be released on June 14, 2019 in the U.S.

Emma Thompson starred in "Beauty and the Beast (2017)" as Mrs. Potts. The 59-year-old actress will next be seen in "Johnny English Strikes Again" which is due out on October 12. She also lands a role in upcoming movie "The Voyage of Doctor Dolittle" as the voice of Polynesia.
