Matt Damon and Kristen Wiig were pictured shooting a scene for their upcoming comedy-drama Downsizing in California Thursday afternoon.

Matt Damon, Kristen Wiig On Set

In the Downsizing set pictures, Damon and Wiig appear to be exiting an airport terminal. Damon is carrying a large red box emblazoned with “Keepsake,” while Wiig is holding a silver shopping bag. Though Wiig is primarily known for her comedic chops, she looked decidedly morose as she made her way into the parking lot. The Bridesmaids star did crack a smile while sipping on a coffee in between takes.

In Downsizing, Damon plays a guy in Omaha who becomes a bit jaded with his life. He decides that he has a better chance at a happy life if he shrinks himself and joins a community of other pint-sized people.

Alexander Payne (The Descendants, Sideways) is directing Downsizing from a script he wrote with Jim Taylor. In addition to Wiig and Damon, it also stars Christoph Waltz, Jason Sudeikis, Neil Patrick Harris and Alec Baldwin.

Downsizing is slated to hit theaters Dec. 25, 2017.
