Marvel unveils new look at "Avengers: Age of Ultron"

The first trailer for "Avengers: Age of Ultron" was supposed to premiere during last night's episode of ABC's "Agents of SHIELD." As we all already know, that didn't happen -- the footage leaked early (Marvel jokingly blamed Hydra) and then the real deal went up online shortly after.

But the studio still gave fans an "Age of Ultron" sneak peek on Tuesday, unveiling a new scene from the upcoming sequel.

The footage showed a party scene where members of the superhero squad take turns trying to lift Thor's hammer. There's a brief moment of panic for the Asgardian hero when Captain America manages to move it ever so slightly, but the best part of the scene is Black Widow's reaction when she's asked to take a turn.

Of course, it's all fun and games until a certain robot named Ultron crashes the fete. Then, the footage segues into the trailer released last week.

This was just one part of a big day for Marvel -- earlier Tuesday, it unveiled its entire film slate through 2019, including two more "Avengers" films and the introduction of new heroes.

"Avengers: Age of Ultron" debuts May 1, 2015.
