If there's one thing the Avengers have, it's issues.
The second trailer for the geek event of the year launched this morning on iTunes, giving fans a coveted first look at a whole lot of new content. What most viewers can draw from it? It's not easy being a super-powered defender of the Universe. Besides the superhero existential angst, the trailer also features extended footage of supervillian Loki and Scarlet Johansson's Black Widow, two major characters who've been relatively MIA from previous teasers.
The Avengers hits US theaters May 4.
