First glimpse of The Avengers trailer - and a hint of more

Here’s the first glimpse of the trailer for the much-anticipated Marvel Studios superheroes movie The Avengers, due in cinemas next May.

Meanwhile cast members Chris Evans (Captain America), Tom Hiddleston (Loki), Clark Gregg (Agent Coulson), Cobie Smulders (Agent Hill) and surprise guest Mark Ruffalo (Bruce Banner, aka The Hulk) and producer Kevin Feige got loud cheers here at the New York Comic-Con as they showed some footage from the film and answered fans' questions.

Feige told fans that Marvel is currently already working on Iron Man 3, which is in pre-production and which he said "will be the first of what we sort of refer to as phase two of this...saga that will culminate, God willing, in Avengers 2."

In its first-ever event at the New York gathering for sci fi and comic book fans, Marvel also screened footage that included an extended scene featuring Ruffalo's Banner as he meets Scarlett Johansson's character Natasha Romanoff, aka Black Widow. 

The footage also included a range of snippets with the other protagonists, such as a scene in which Robert Downey Jr.'s Tony Stark aka Iron Man tells Loki that he has annoyed a range of his superhero colleagues.
