Marvel Studios has released the first full-length trailer for its eagerly anticipated superhero movie mash-up The Avengers. Written and directed by geek messiah Joss Whedon, the film is the true story of eight superheroes picked to live in a house, work together and have their lives taped to find out what happens when heroes stop being polite… and start getting real.

The Avengers all-star cast includes Robert Downey Jr. (Iron Man), Scarlett Johansson (Black Widow), Chris Hemsworth (Thor), Chris Evans (Captain America), Jeremy Renner (Hawkeye), Samuel Jackson (Nick Fury), Mark Ruffalo (The Hulk), Tom Hiddleston (Loki), Gwyneth Paltrow (Pepper Potts), Cobie Smulders (Maria Hill) and—of course—Ralph Fiennes and Uma Thurman as John Steed and Emma Peel.
