franchises were previewed at the event.

The cast of upcoming Marvel movies "Avengers: Age of Ultron" and "Ant-Man" met at the event

to walk the red carpet and host Q and A panels.

Robert Downey Jr. seemed delighted to be reunited with his co-stars.

The greatest thing about this is, I really love these folks, like I really have become

close with these people, we don't just hang out on press lines you know, they're like

family to me.

And it's quite an experience according to the Hulk himself Mark Ruffalo.

You know, you come out here and oh, you've seen everything, done, you know, maybe I've

done everything and then you experience this kind of love and this kind of adoration and

it's very humbling, you know. It's very, it's very satisfying and, actually, it sort of

re-sets your sense of wonder and innocence and reminds you, oh, now I know why, I remember

why I did this and why I love to do this.

Samuel L Jackson admitted he thinks superheroes are an important part of society.

For a long time we had Buck Rogers and then there was Superman, you know, the television

show, the movie started to show and all of a sudden we figured out how to get people

with real super powers on screen. And, everybody has a fantasy about flying or being stronger

than everybody else or having some kind of power that they could use and it feeds into

everybody's fantasies of being more than what we are. And I like that and I like a world

like that. So, it's great for us to inhabit it and you know, bring it to life for people.

And, I want to see myself in those things.

Avengers: Age of Ultron" and "Ant-Man" are released in 2015.
