Both Thompson and Hemsworth posted photos to their Instagram giving us a first look at the new MIB stars.
This isn't the first time the two have acted together.
Last time fans saw them was playing Thor and Valkyrie in Thor: Ragnarok.
Now they take on the roles of Agent H—Hemsworth—and Agent M—Thompson.
The film is billed as a spin-off as opposed to a sequel.
The cast includes Emma Thompson—reprising her role as Agent O from 2012's Men in Black 3—as well as Liam Neeson, Rebecca Ferguson, Rafe Spall and Kumail Nanjiani.
People were here for it.
F. Gary Gray takes over as director from Barry Sonnenfeld who helmed all three prior Men In Black films. Gray previously directed The Fate of the Furious, The Italian Job and Straight Outta Compton. Matt Holloway and Art Marcum—who wrote Iron Man for Marvel Studios—provided the script for the spin-off.
More than a few people asked for a tie-in with aliens Thor and Valkyrie working for an Earth—or is it Midgard—agency that tracks aliens living on our planet.
The spin-off is slated for a June 2019 release.
The countdown begins!
