The Avengers

“Some assembly required.”

Nobody at S.H.I.E.L.D. saw this enemy coming, and Nick Fury has no one in place to stop it. So he starts recruiting across the globe: Tony Stark (Robert Downey Jr.), Steve Rogers (Chris Evans), Bruce Banner (Mark Ruffalo), Thor (Chris Hemsworth) and Natasha Romanoff (Scarlett Johansson). Joss Whedon gives each of them a stretch of screen, and the problem is whether people this different can work as a team.
