Marvel Studios dropped a full-length trailer for Captain America: Brave New World at the Brazil D23 fan event this weekend.

This is star Anthony Mackie’s first cinematic appearance as the new Captain America after the Phase Four 2021 TV miniseries, The Falcon and the Winter Soldier. In addition to Mackie and Ford, the cast includes Liv Tyler as the president’s daughter, Betty Ross, and Tim Blake Nelson as Samuel Sterns, both reprising their roles in 2008’s The Incredible Hulk. (Ford replaces the late William Hurt, who played Ross in that earlier film.) Carl Lumbley plays Isaiah Bradley, reprising his F&WS role as a Korean War veteran who had been secretly imprisoned and given the Super Soldier Serum against his will, enduring 30 years of experimentation. (He told Sam he couldn’t imagine how any black man could take up Captain America’s shield because of what it represented to people like him, and one could hardly blame him.) Rosa Salazar plays Rachel Leighton, Danny Ramirez plays Joaquin Torres, and Shira Haas plays Ruth Bat-Seraph. Giancarlo Esposito will also appear as Sidewinder, the alter ego of economics professor Seth Voelker, who gains the power of teleportation via a cloak (a gift from the Egyptian god Set) and forms a criminal organization called The Serpent Society in the comics.

The new trailer opens with Sam/Captain America visiting Isaiah in prison; Isaiah doesn’t remember what he’s supposed to have done, but the trailer shows us his involvement in an attempted assassination of President Ross. “Whatever this is, Cap, be careful,” Isaiah tells Sam. We learn there were five shooters in a coordinated terrorist attack. Sam is determined to get to the bottom of things to fend off the breakout of a war. But the rabbit hole looks like it might run pretty deep when Sam gets a phone call asking, “Do you ever wonder who’s playing who?” Someone else is pulling the strings and Sam looks like he’ll be framed at some point as well. The trailer ends with Ross’s full transformation into Red Hulk and a head-to-head battle with Sam.
