At the New York Comic Con Saturday panel for The Avengers — which included Marvel Studio Head Kevin Feige and actors Chris Evans (Captain America) and Mark Ruffalo (Bruce Banner/The Hulk) — the enthusiastic audience was treated to a scene from the eagerly anticipated Marvel team up.

The clip showed how Banner, who is in hiding, gets recruited into the Avengers by the sultry Natasha Romanoff, aka the Black Widow (Scarlett Johansson). To avoid being a spoiler, it’s safe to say the Black Widow doesn’t send Banner an Evite.

When asked to join the superhero group — which will ultimately include Captain America, Thor and Iron Man — the suspicious Banner asks, “What if I say no?” Romanoff replies that she’ll persuade him. Referring to his alter ego, Banner’s threatens, “What if the other guy says no?”

From the scene and the panelists, which also included Tom Hiddleston, who plays Thor’s evil brother Loki, Marvel fans also learned that in the movie:

1. The Avenger’s must unite to fight a global threat.
2. Loki is the primary villain.
3. That while Mark Ruffalo’s interpretation of Banner will pay homage to the previous actors who have played the role — including Bill Bixby, Eric Bana and Edward Norton — Ruffalo’s take on the character is completely new.

Ruffalo’s Banner seems more aggressive, more confident and less tortured by the ever-present threat that he can become a monster. His Banner actually seems to enjoy his potential power. According to the actor, Banner “understands a little more [about] what he has under the hood.”

Ruffalo proudly announced that, with the aid of sophisticated motion-capture technology, he will be the first actor to play both Bruce Banner and the Hulk.

Marvel Studio’s traditional post-credits scene in The Avengers will tease an upcoming Marvel film — presumably Iron Man 3.
