"Thor: Ragnarok" co-stars Tessa Thompson and Chris Hemsworth are filming another movie together, and it looks like they're enjoying the reunion.

The two have teamed up for an upcoming "Men in Black" spinoff, and production is underway. They gave fans a glimpse of what they're up to by sharing photos via Instagram on Sept. 20. We can't glean a whole lot from them, but we can see that Thompson and Hemsworth are really rocking their suit-and-tie combination as their secret agent characters.

Hemsworth posted first, and he shared a photo where they both have on their serious (maybe sultry?) faces.

Apparently, it was a whole selfie photo shoot, because a few hours later, Thompson posted an image that must have been taken around the same time as Hemsworth's. In it, her expression is very similar to the other, but her co-star got a little silly and made fish lips for the camera.

Production seems to be off to a good start. The two star in the F. Gary Gray-directed film alongside Liam Neeson, Emma Thompson, Kumail Nanjiani, and Rafe Spall.

The movie is due out June 14, 2019.
