Marvel mainstays Anthony and Joe Russo have shared another look at their upcoming crime-thriller.

During their Comic-Con panel discussion on Friday, the brothers blessed the audience with the second trailer for 21 Bridges, led by Black Panther star Chadwick Boseman. The 41-year-old plays NYPD detective Andre Davis, who essentially closes off the island of Manhattan in an effort to capture a pair of suspected cop-killers. As Davis goes deeper into the case, he realizes the crime was part of a much larger conspiracy that may involve corrupt officers.

"When I read the script, I could tell that it was going to be a ride," Boseman told Variety about 21 Bridges. "It took me back to my theater days when you have the fast-paced language like David Mamet."

In preparation for the film, Boseman went on a number of NYPD ridealongs, which he described as somewhat of a rollercoaster: "At times it was a lot of fun, [but] it was horrific some of the things that you experience."

The Brian Kirk-directed  film—co-produced by Boseman and the Russo brothers—also stars Sienna Miller, Keith David, Taylor Kitsch,  J.K. Simmons, and Stephan James of 2018's If Beale Street Could Talk.

You can watch the second 21 Bridges trailer above. The film opens in theaters on Sept. 27.
