Robert Downey Jr., Avengers on Parade in New Trailer (watch!) 1Scarlett Johansson, Robert Downey Jr. and the team of actors who play the Avengers have been assembled for the first time in a new trailer that promises worldwide cataclysm.

Marvel released the first full-length trailer for the highly anticipated film and judging from early reaction it has a lot to live up to.

The testosterone-laden film also stars Chris Evans, Mark Ruffalo, Chris Hemsworth, Jeremy Renner and Samuel L. Jackson.

The four main heroes The Hulk, Iron Man, Captain America and Thor all make cameos in the trailer with appearances by Nick Fury, Black Widow, Hawkeye and the evil Loki.

Considering that expectations for the film are high, fan disappointment is lurking at every turn in the trailer.

“Given the scope and impact of the individual films, how does this one deliver something bigger, better, newer?” writes The Hollywood Reporter’s Jay Fernandez.

“it would have been all too easy for the trailer to disappoint. However, I think you’ll agree that this sneak peek was custom-designed to both whet our appetites and leave us clamoring for more,” writes Linda Sharps, of the blogging site The Stir.

In movie, Nick Fury, director of the peacekeeping organization S.H.I.E.L.D., recruits Iron Man, Hulk, Thor, and Captain America to save the world from nothing less than total destruction.
