As we see in the firstComic-Contrailer,21 Bridgesfollows an embattled NYPD detective (Chadwick Boseman), who is thrust into a citywide manhunt for a pair of cop killers after uncovering a massive and unexpected conspiracy. As the night unfolds, lines become blurred on who he is pursuing, and who is in pursuit of him. When the search intensifies, extreme measures are taken to prevent the killers from escaping Manhattan as the authorities close all21 Bridgesto prevent any entry or exit from the iconic island.

In order to properly prepare for21 Bridges, Chadwick Boseman went out on patrols with real NYPD officers. This is a common practice for actors whengetting ready for a police officer role, but it looks like Boseman went pretty deep into the process. He recently spoke about his preparation process and how it affected him. Boseman had this to say.

“At times it was a lot of fun hanging out with them; at other times it was horrific, some of the things you experience. One of the things they talked about a lot was how the job affects them personally - how the job takes over their entire lives, and I think that’s an element of this film that we try to stay true to.”

In addition to Chadwick Boseman,21 Bridgesalso stars Sienna Miller, Stephan James, Keith David with Taylor Kitsch, and J.K. Simmons. Joe and Anthony Russo also recently talked about the upcoming movie and what viewers can expect when venturing into theaters to check it out. Joe Russo had this to say about21 Bridges.

“The Winter Soldieris an example of how thrillers were really important to our cinematic upbringing and this one is awesome. I mean, it’s intense. The action is fantastic. It’s the kind of movie that they’re, I feel like they’re not really making a lot of anymore. It’s a real throwback to a 70’s thriller. It’s, it feels like a Lumet movie.”

21 Bridgeshits theaters on September 27th, and if the latest Comic-Con trailer is any indication, it’s going to be an intense ride, full of psychological twists and turns. Chadwick Boseman will soon be getting back to Wakanda and the Marvel Cinematic Universe whenBlack Panther 2begins shooting.
