Avengers Age of UltronIf the first two trailers for "Avengers: Age of Ultron" got you excited for the Marvel movie, buckle your seat belt for the third one!

Marvel released a new, final trailer featuring a ton more footage of Iron Man, Captain America, the Hulk, the Black Widow, and Hawkeye in action. We get better looks at some of the movie's big action setpieces - road chases, infrastructure destruction, odds-are-against-them battles - as well as more glimpses of Ultron, Scarlet Witch, and Quicksilver.

And there's a bit of foreshadowing for "Captain America: Civil War," as Tony Stark (Robert Downey, Jr.) and Steve Rogers (Chris Evans) seem to be at odds over why they do what they do.

"Avengers: Age of Ultron" opens in theaters May 1.
