Frankly, I've always been a bit scathing of these big screen action men - the Jason Bournes, James Bonds, Austin Powers (baby!) of this world, most recently the Jeremy Renners. After a while, they all seem to stop smiling in photos, like they've started believing they are actually secret agents in real life, not grown men fighting for mirror-space of a morning, and getting their hair professionally blow-waved.
Ever since Samuel L. Jackson first popped up as Nick Fury in the end credits of Iron Man back in 2008, fans the world over have been eagerly awaiting the time when the one-eyed Director of S.H.I.E.L.D. would bring together these superheroes for the holy grail of comic book movies. Well Marvel fans, the time has come.
