New Avengers Black Widow Scene Online

Scarlett Johansson sits down, kicks ass

If you're hoping to watch Avengers Assemble later this month without having seen anything from it beforehand, click away now - because we've got 43 seconds of ass-kicking here you may want to wait to see on the big screen.

Still with us? Good. As you can tell from the grab below, the snippet Marvel has released centres on Scarlett Johansson's Black Widow making a phone call with her hands tied behind her back.

Now, though that's kinda-sorta-not-really that remarkable, it's what she gets up to after hanging up on Agent Coulson that's much, much, much more impressive.

Seriously, who knew you could hurt that many people while still (technically) sitting down? And, at one point, using just your hair?

And just to remind you of the previous trailers and teasers, here they are for you below.

Avengers Assemble - as the official title now reads in the UK - is out in the UK on April 26.
