Footage of "Captain America: The Winter Soldier" that has been presented to fans at the San Diego Comic-Con and Disney's D23 expo has now leaked online. The clip for Anthony and Joe Russo's upcoming movie briefly teases a fighting scene that happens inside an elevator.

The Cap, played by Chris Evans, is standing in his new suit, with some bad guys, dressed in black, surrounding him. "Before we get started," the titular hero says, and the next shot gives a clear look at his shield attached to his back. He continues, "Does anyone want to get out?" and right after this, the chaos starts.

"The Winter Soldier", written by Christopher Markus and Stephen McFeely, will follow Steve Rogers struggling to embrace his role in the modern world and team up with Natasha Romanoff, a.k.a. Black Widow, to battle a powerful yet shadowy enemy in present-day Washington, D.C.

Scarlett Johansson and Samuel L. Jackson reprise their roles as Black Widow and Nick Fury respectively. Portraying the Winter Soldier is Sebastian Stan, who also starred in the first installment. Robert Redford is on board to be a senior leader within the S.H.I.E.L.D. organization.

"The Winter Soldier" is scheduled to arrive in U.S. theaters on April 4, 2014.
