One Last 'Avengers: Age Of Ultron' Trailer Spotlights Black Widow

For all the talk about how Furious 7 officially marked the start of the movie season this year, April's actually a pretty mellow month for wide releases. May is when the action really gets going, starting with Avengers: Age of Ultron.

Marvel has not been stingy about releasing footage for this highly anticipated superhero team-up. And while they're bound to run out eventually, they've managed to squeeze out a little bit more for a final promo. Check out one more Avengers Age of Ultron trailer after the jump.

IMDb unveiled the latest, and likely last, Avengers Age of Ultron trailer. Much of this is recycled footage from previous trailers, but there's some cool new stuff mixed in as well.

This trailer is all about fun, in contrast to some of the earlier ads that have focused on the gravity and seriousness of the situation. It also puts shifts the focus to Scarlett Johansson's Black Widow. She may not have her own eponymous film series, the way teammates Captain America, Thor, and Iron Man do, but she's nevertheless emerged as one of the franchise's most popular characters. It's especially entertaining to see her team up with Cap here, since it was about a year ago that Winter Soldier established the growing friendship between them.

Avengers Age of Ultron opens May 1.

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.
