Avengers: Age of Ultron begins in media res, with the usually fractious superheroes seemingly having evolved into a well-oiled, super-powered machine as demonstrated by a coordinated attack on HYDRA and its new leader Baron Von Strucker (Thomas Kretschmann). Thor (Chris Hemsworth) is beating whole flocks of HYDRA soldiers with one swing of his hammer, Mjolnir. Captain America (Chris Evans) uses his motorcycle the way a gymnast would a balance beam, pushing off into acrobatic flips and bowling his enemies over before meeting the cycle again further down the line. The Hulk (Mark Ruffalo, or a CGI version of him) simply barrels through the bad guys like a runaway train while the Black Widow (Scarlett Johansson) follows close behind, prepared to execute a secret "lullaby" protocol that mysteriously calms the green behemoth in nearly an instant. All of this unfolds while Iron Man (Robert Downey, Jr.) is at his most detached, ordering his new Iron Legion of robots to do most of the dirty work while he flies overhead, trying his best to break through an invisible force field surrounding Strucker's castle.
