Lucasfilm has moved to bring in another new cast member for its still-untitled Han Solo movie.

As broken by Variety, this next Star Wars Story effort has added Michael K. Williams to its ranks. The actor, best known for The Wire, Boardwalk Empire, the RoboCop reboot and Assassin’s Creed, has landed an unspecified key role.

Williams joins a cast that includes Alden Ehrenreich as the young Han, Donald Glover as the young Lando Calrissian, Joonas Suotamo as Chewbacca, and unknown roles for Woody Harrelson, Emilia Clarke, Thandie Newton and Phoebe Waller-Bridge.

To be directed by The LEGO Movie’s Phil Lord and Christopher Miller, the still-to-be-titled picture will tell the story of how Han Solo came to be the scruffy-looking nerf-herder we were all introduced to in Mos Eisley back in 1977.

At present, this Solo-centric film is set for a May 25th, 2018 release.
