Although The Avengers are collectively known as Earth's Mightiest Heroes, one of them does not hail from this planet. That hero, of course, is the mighty Asgardian warrior Thor (Chris Hemsworth), whose mystical connection to the hammer Mjolnir is tested by the rest of the team in the first of two clips from Avengers: Age of Ultron. Thor is happy to watch as the rest of his teammates try to simply lift Mjolnir from its resting place, even though anyone who does so will rule over Asgard. While no one can fully wield Mjolnir, Thor is given a moment of pause when Captain America (Chris Evans) is actually able to make the hammer budge, ever so slightly.

The second clip features Black Widow (Scarlett Johansson) trying to get Bruce Banner (Mark Ruffalo) to trust him, after Bruce's huge green alter-ego helped the team achieve their latest victory. Banner still does not trust himself as the Hulk, and the situation does not improve when Black Widow asks Thor for a report on the Hulk's performance. The Asgardian replies with a hilariously insensitive comment that he immediately tries to retract.

Avengers: Age of Ultron is the epic follow-up to the biggest Super Hero movie of all time. When Tony Stark tries to jumpstart a dormant peacekeeping program, things go awry and Earth's Mightiest Heroes, including Iron Man, Captain America, Thor, The Incredible Hulk, Black Widow and Hawkeye, are put to the ultimate test as the fate of the planet hangs in the balance. As the villainous Ultron emerges, it is up to The Avengers to stop him from enacting his terrible plans, and soon uneasy alliances and unexpected action pave the way for an epic and unique global adventure. Check out the new clips below, as we continue to count down the days until this action-packed epic adventure hits theaters on May 1.
