Filming for "Captain America: The Winter Soldier" is in full swing up there in Cleveland, Ohio, and thanks to the natives* (go Browns?), we've gotten some pretty neat-o little sneak peeks at that titular bad guy in street action.

You may not quite recognize him, but that's totally Sebastian Stan there filming scenes for "Captain America 2." Long gone is Steve Rogers' (Chris Evans) formerly faithful soldier sidekick, Bucky Barnes.

Of course, a few decades of being left for dead in the freeze tank and then subjected to Russian mind-tinkering'd throw just about anybody off — or onto, depending on how you look at it — their A-game.

So, here's Stan's assassin passion in action (read: climbing on the hood of a gas-guzzle-mobile) Downtown this afternoon. You can't quite see it in this shot, but from this angle, the dude's bionic arm is totes on display in the scene.

This aerial vid from Friday's filming session shows that he'll be ripping the door right off of that Hummer on-screen.

For good measure, here are a coupla more look-sees at Stan throwin' down on the street last Friday.
