According to THR, the film “will be a global adventure.” No other plot or character details have been revealed at this time; however, we do know that the spinoff will be based off of the science-fiction world created in the original films starring Will Smith and Tommy Lee Jones. Per THR sources, “Sony is hoping to round out a diverse ensemble cast and may be potentially eying the leads to be white male, a female of color, and an older man.”
The original franchise, including three films total, grossed over $1.5 billion worldwide. The spinoff will see original trilogy producers Walter F. Parkes and Laurie MacDonald returning and Steven Spielberg executive producing.
Hemsworth can most recently be seen in the Jerry Bruckheimer-produced 12 Strong and the forthcoming Avengers: Infinity War, whose trailer you can watch here. Gray recently directed The Fate of the Furious but is best known for his Oscar-nominated Straight Outta Compton and the Italian Job remake with Mark Wahlberg and Charlize Theron.
The new Men in Black spinoff is slated for a June 14, 2019 release, so hopefully once casting is complete, it will be smooth sailing for this project.
