The first trailer for May 2012's The Avengers is here, and it's exactly as you'd expect — action-heavy with some sardonic asides, as is Joss Whedon's wont. The trailer has the requisite car explosions and slow-motion helicopter whuh-whuh-ing for your attention, plus Robert Downey Jr. sure gets some good zingers. Listen closely and you can hear Scarlett Johansson say something! Just kidding, no you can't. Jeremy Renner's bow and arrow seem pretty flimsy compared to Samuel L. Jackson's shoulder-mounted gigantic gun, but then again, everyone's charisma and presence seem flimsy compared to Downey's magical swagger.
