Following a widely shared trailer leak last week, Marvel had gone ahead and decided to publish an official teaser trailer before they can show it during S.H.I.E.L.D. Anyhow, during tonight’s episode of Agent of S.H.I.E.L.D., ABC aired the extended trailer from Avengers: Age of Ultron with some new footage added into the trailer we already saw.

A minute long bonus clip gives more insight into what the Avengers will be up against. It features the team celebrating at Tony Stark’s penthouse, and eventually attempting to lift Thor’s Mjolnir when the first Ultron model appears from the shadows and says:

‘How could you be worthy. You’re all just puppets, dangled by strings. Strings.’

Joss Whedon’s highly anticipated Marvel Studios sequel opens in theaters on May 1, 2015.

Check out the shenanigans from the Avengers below:

This must be a spoof, right? Because that was pathetic. I hope we see Cap wield that hammer by the end of Age of Ultron. Imagine what Hulk could’ve done. Anyhow, dive into the official synopsis for Avengers: Age of Ultron:

Marvel Studios presents “Avengers: Age of Ultron,” 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.

Marvel’s “Avengers: Age of Ultron” stars Robert Downey Jr., who returns as Iron Man, along with Chris Evans as Captain America, Chris Hemsworth as Thor and Mark Ruffalo as The Hulk. Together with Scarlett Johansson as Black Widow and Jeremy Renner as Hawkeye, and with the additional support of Samuel L. Jackson as Nick Fury and Cobie Smulders as Agent Maria Hill, the team must reassemble to defeat James Spader as Ultron, a terrifying technological villain hell-bent on human extinction. Along the way, they confront two mysterious and powerful newcomers, Wanda Maximoff, played by Elizabeth Olsen, and Pietro Maximoff, played by Aaron Taylor-Johnson, and meet an old friend in a new form when Paul Bettany becomes Vision.

Written and directed by Joss Whedon and produced by Kevin Feige, Marvel’s “Avengers: Age of Ultron” is based on the ever-popular Marvel comic book series “The Avengers,” first published in 1963. Louis D’Esposito, Alan Fine, Victoria Alonso, Jeremy Latcham, Patricia Whitcher, Stan Lee and Jon Favreau serve as executive producers. Get set for an action-packed thrill ride when The Avengers return in Marvel’s “Avengers: Age of Ultron” on May 1, 2015.
