Filming is under way in Cleveland on Captain America: The Winter Soldier, and some new set photos and videos have surfaced to tease the upcoming Marvel sequel. In the below video, police and S.W.A.T. teams can be seen taking part in a shootout set in Washington, D.C.

It's unclear just who is involved in the shootout, but it seems like Samuel L. Jackson's Nick Fury might be. He was also photographed on set as law enforcement officials fired on a black SUV. S.H.I.E.L.D.'s role hasn't been entirely revealed in this new movie, so it's unclear if he's helping the police subdue an enemy or is the one being fired on himself.

Jackson joins returning cast members Chris Evans (Captain America/Steve Rogers), Sebastian Stan (Bucky Barnes/Winter Soldier) and Toby Jones (Arnim Zola), along with Cobie Smulders (Maria Hill), Scarlett Johansson (Black Widow), Anthony Mackie (Sam Wilson/Falcon), Emily VanCamp (Sharon Carter), Frank Grillo (Crossbones), Max Hernandez (Agent Jasper Sitwell) and Robert Redford.

Directed by brothers Anthony and Joe Russo, Captain America: The Winter Soldier is believed to be based on the Captain America storyline of the same name, which revealed Captain America’s sidekick Bucky Barnes didn’t die as expected during the war. Instead, an amnesiac Bucky got snatched by the Soviets, fitted with a bionic arm and programmed to serve as an assassin known as the Winter Soldier. The secret is revealed in the present day after Barnes attacks the Red Skull and blows up part of Philadelphia. The film opens in 3D on April 4, 2014.
