Watch the new 'Avengers: Age of Ultron' trailer now

"Avengers" fans, Christmas came early this year. Here's the brand new trailer for "Avengers: Age of Ultron," released by Marvel Wednesday.

We don't want to judge a book by its cover (or a movie by its trailer), but this installment looks even more action-packed than the last.

Set to an eerie take on the Pinocchio song "I've Got No Strings," the dark trailer has plenty for fans to get excited (or worried) about.

We got a look at the entrance of Scarlet Witch (Elizabeth Olsen) and Quicksilver (Aaron Taylor-Johnson). Members of the Avengers team are battle-weary and fighting amongst each other, with Tony Stark's Hulkbuster armor trying to hold its own against the giant, green behemoth himself. Finally, of course, the title villain Ultron dominates, giving a terrifying speech about why the Avengers will never defeat him.

The trailer was originally scheduled to be released during the Oct. 28 episode of "Agents of S.H.I.E.L.D." which also takes place in the Marvel universe and which is created by Joss Whedon, the same man behind both "Avengers" movies.

When the movie was leaked online Wednesday night, though, Marvel didn't ignore it. They played along, tweeting a joke about their frustration.

Marvel then officially released the teaser trailer, along with a teaser poster.

"Avengers: Age of Ultron" hits theaters May 1, 2015.

Disney is the parent company of both Marvel and this station.
