Chris Hemsworth, Thor, Thor: RagnarokMarvel Studios

Chris Hemsworth is officially a Man in Black.

We'll see Hemsworth back as Thor in "Avengers 4," but next up he's filming the 2019 "Men in Black" spinoff alongside "Thor: Ragnarok" friend from work Tessa Thompson. Filming just began in London, and Hemsworth was spotted Sunday on set.

According to That Hashtag Show, Hemsworth plays suave and goofy Agent H in the London branch of the MIB. Thompson plays Molly (Agent M?), who is aware of the existence of aliens and wants to join the MIB. Liam Neeson plays the head of the London office. The agents "become involved in a murder mystery that has them traveling the globe."

JustJared shared a bunch of photos of Hemsworth walking around the London set in a suit and shades.

Kumail Nanjiani also co-stars as Pawny, "a funny, wise-cracking, sex-driven alien from a civilization that exists on a Chessboard." Actor Rafe Spall and dancers Les Twins were also reportedly cast for the film, which is being directed by F. Gary Gray.

"MIB" -- or whatever they end up calling it -- is scheduled for release in theaters on June 14, 2019.
