It's no surprise he's in line for the MiB gig: with the hilarious Taika Waititi at the helm of Thor: Ragnarok, Hemsworth was able to show off the comedic chops that should fit neatly into the new franchise.
Hemsworth's role would be part of a starring ensemble alongside "an older man" and "a woman of color" would go on a global adventure. A release date of June 14, 2019, has already been set. The new venture looks to be going back to its original premise of a covert force policing the alien population hiding in plain sight, the premise of the comic book series by Lowell Cunningham and Sandy Carruthers.
The original film saw Jones and Smith as two agents from a secret organization known as the "Men in Black", who were responsible for deterring extraterrestrial terror from ravaging Earth. It will build on the contemporary sci-fi world established in the first three movies, much like "Jurassic World" did with its franchise.
