Marvel Studios delivers the ultimate comic-book production, tying such characters as IRON MAN (Robert Downey Jr.), CAPTAIN AMERICA (Chris Evans), THE HULK (Mark Ruffalo), & THOR (Chris Hemsworth) together for a big-screen franchise team-up like no other. Taking centre stage this time is Nick Fury (played once again by the note-perfect Samuel L. Jackson), leader of the peacekeeping agency known as S.H.I.E.L.D. Fury, along with former Russian spy Black Widow (Scarlett Johansson), recruits a super team to combat Thors ever-deceptive brother Loki (Tom Hiddleston) after he brainwashes ace archer Hawkeye (Jeremy Renner) while stealing a cosmic cube from an underground base. Thus the heroes must learn to work together alongside outlaw scientist Bruce Banner (Ruffalo), who can track down the artifacts gamma signals when hes not hulking out into a giant green monster. Show runner Joss Whedon (BUFFY THE VAMPIRE SLAYER, FIREFLY) adapted & helmed the script by Zak Penn.
