UPDATE: Watch the new, full-length "Captain America: The Winter Soldier" trailer now!

Right, so the whole "trailer for a trailer" thing is still happening, and the latest one is for tomorrow's "Captain America: The Winter Soldier" trailer premiere.

The approximately 10 seconds of teaser footage shows Steve Rogers (Chris Evans) hurtling through an office, as well as glimpses of Scarlett Johansson's Natasha Romanoff/Black Widow and Samuel L. Jackson's Nick Fury. There's also a peek at someone who looks to be Sebastian Stan as Bucky Barnes/Winter Soldier, a brainwashed assassin who battles Captain America.

In Marvel's "Captain America: The Winter Soldier" -- set two years after "The Avengers" -- Steve is trying to adapt to the modern world when he's pulled into solving a conspiracy after a S.H.I.E.L.D. agent is compromised. He and the Black Widow recruit the Falcon (Anthony Mackie) to unravel the mystery before it endangers the world.

The movie also stars Cobie Smulders, Hayley Atwell, Emily VanCamp, Toby Jones, and Robert Redford, and opens in theaters April 4, 2014.

Rest assured, the full trailer will be available on Moviefone tomorrow.
