Marvel has premiered the much-anticipated trailer for "The Avengers," the Joss Whedon-directed epic adventure that brings together the major players of the studio's cinematic universe.

The two-minute teaser handily establishes the movie's premise, with Samuel L. Jackson's Nick Fury laying out a vision for "a group of remarkable people" to "fight the battle we never could." In this case that battle is with Loki (Tom Hiddleston), who intones, "You were made to be ruled. ... In the end, it will be every man for himself."

The trailer is, of course, heavy on the assembling, but fans are also treated to plenty of action, as well glimpses of Iron Man's new armor and, best of all, the new take on the Incredible Hulk. Naturally, Robert Downey Jr.'s Tony Stark gets the best lines, whether it's bumping heads with Chris Evans' Captain America, complimenting Mark Rufallo's Bruce Banner on his ability to lose control, or solemnly vowing, "If we can't protect the Earth, you can be damned sure we'll avenge it."
