The Russo brothers may be done with the Marvel Cinematic Universe (for now), but they're still working with members of the "Avengers" team.

At a Comic-Con panel today, the filmmaker brothers unveiled a new trailer for their next producing project, the crime thriller "21 Bridges," starring Chadwick Boseman.

Directed by Brian Kirk, the film follows an NYPD detective who is thrust into a citywide manhunt for a pair of cop killers after uncovering a massive and unexpected conspiracy. Determined to catch the killers, Boseman goes to extreme lengths, including shutting down bridges and closing tunnels — basically locking the whole city of Manhattan down.

Over the course of the night, lines become blurred on who he is pursuing — and who is in pursuit of him.

The movie also stars Sienna Miller, Stephan James, Keith David, Taylor Kitsch and J.K. Simmons.

After "Avengers: Endgame," Boseman has been very busy. His next projects is Spike Lee's Netflix join "Da 5 Bloods." And we fully expect a sequel to "Black Panther" at some point.

"21 Bridges" opens in theaters September 27.
