The first Avengers: Age of Ultron trailer for writer/director Joss Whedon’s highly anticipated superhero follow-up has leaked online under a week before its official release. The sequel finds Iron Man (Robert Downey Jr.), Captain America (Chris Evans), Black Widow (Scarlett Johansson), Thor (Chris Hemsworth), Hulk (Mark Ruffalo), and Hawkeye (Jeremy Renner) teaming up once again to battle the devious robot known as Ultron (James Spader). This is very close to the footage that was shown at Comic-Con, save for a different final shot and an extended clip that was shown of the so-called “Avengers Party.” What’s clear from this trailer is that the tone is darker, the stakes are higher, and the threat is seemingly more nefarious.
Watch the trailer after the jump. Avengers: Age of Ultron also stars Elizabeth Olsen, Aaron Taylor-Johnson, Paul Bettany, Don Cheadle, Andy Serkis, and Samuel L. Jackson and opens in theaters May 1, 2015.
