The first clip from Joss Whedon's The Avengers has gone online.  In the clip, Natasha Romanoff aka "Black Widow" (Scarlett Johansson) demonstrates proper phone etiquette before showing that she doesn't need superpowers to kick ass (unless you count boob-jiggling as a superpower, which I do).  Also, Agent Coulson (Clark Gregg) mentions that "Barton has been compromised."  For those who don't understand the reference, Barton is Clint Barton aka "Hawkeye" (Jeremy Renner).The clip is very Whedonesque with Natasha's flippant attitude towards her captors, and the knowledge that she's about to bust out and beat them up.  It's a scene that easily could have been ripped from Buffy, Angel, or Firefly (I haven't watched all of Dollhouse so I'm not sure on that one).  Hit the jump to check out the clip.  The film also stars Robert Downey Jr., Chris Evans, Chris Hemsworth, Mark Ruffalo, Tom Hiddleston and Samuel L. Jackson.  The Avengers opens in 3D on May 4th.  If you missed them on Monday, click on the corresponding links for our set visit, and interviews with Robert Downey Jr., Chris Evans, Chris Hemsworth, Jeremy Renner, Scarlett Johansson, Tom Hiddleston, Mark Ruffalo, Clark Gregg, Marvel Studios President of Production Kevin Feige, and writer-director Joss Whedon.Clip via Marvel.  Here's the official synopsis for The Avengers:
