The first film featuring Marvel's gang of heroes fighting the good fight cleared more than a billion dollars at the global box-office. The knock-on effect was the huge success of the second Captain America film, Winter Solider, which made pretty close to that - despite a poor first effort. 

Now, the third trailer has dropped ahead of its end of April release, and well... just watch it. 

Joss Whedon did a superb job with the first film and Marvel generally are handling their properties very well. Trailers have all been extremely impressive so far too. 

We can't wait for this to open...
