I think maybe interest in the new teaser trailer for “Captain America: The Winter Soldier” broke iTunes today.

At any rate, the trailer didn’t play on the iTunes site for nearly an hour after its scheduled noon release.

It’s working now, however, but here are some highlights:

Plenty of Robert Redford, looking great as the head of SHIELD. Yes, even above Samuel L. Jackson’s Nick Fury.

Cap (Chris Evans) looking worried, and rightly so.

Cap and Nick Fury.

Cap’s got to watch his back.

SHIELD’s helicarrier has its own problems.

Cap’s got trusted allies, including Sam Wilson, AKA The Falcon.

And Natasha, The Black Widow.

An old ally returns as The Winter Soldier.

Which leads to conflict with Cap.

And an ultimate showdown?

Here’s the trailer.

I can’t wait for April 4.
