While fans got a taste of "Avengers 2: Age of Ultron" from its teaser at Comic-Con this summer, the Fall is here and anxious fans want more tidbits. Producer and director Joe Russo ("Captain America") reportedly commented on the "Avengers 2" teaser.

"We've seen what everyone else has seen that was at Comic-Con. We saw that incredible two minutes of footage from it. It looks like the biggest movie ever made, so we're very excited for it. We have read the script. It's incredible. I think Joss [Whedon] is going to blow people away with this one,” Russo told the Wall Street Journal.

As previously reported, "Avengers 2: Age of Ultron" stars Robert Downey Jr., Jeremy Renner, Mark Ruffalo, Chris Hemsworth, Samuel L. Jackson, Chris Evans, Cobie Smulders, Aaron Taylor-Johnson, Scarlett Johansson, Paul Bettany, James Spader, and Elizabeth Olsen, as well as Marvel Studios chief Kevin Feige.

“Avengers 2” director Joss Whedon chimed in, saying that the sequel will be "a little scarier, a little funkier, but in the end they're still the same extraordinary characters. And a lot of humor and yes ... there will be some punching,” Movie Pilot reports.

In addition, the plot reveals that "Avengers 2" will reportedly be "much darker" than the first film. Also, more rumors have surfaced.

"Digest has offered new angles and a few interesting details on how the sequel's direction could take a new turn. We've been hearing bits of Carol Danvers, aka Ms. Marvel, who might sneak in a part at Age of Ultron," Movie Pilot adds.

"A statement from Badass (reportedly taking from an early draft of the script) gives key details (via Screencrush): At the end of 'Age of Ultron' Cap will assemble a team that is a mix of familiar and new faces, leading forward into Phase Three. It's an exciting mission statement for Marvel Studios, letting audiences know that the Avengers team is more than just the guys who were in the first film.

"The make-up of that team is, technically, up in the air until that scene is shot (I suspect it's being saved for either scheduled reshoots or will be snuck into the schedule of 'Captain America 3,' which goes before cameras early next year), but Joss Whedon's script did indicate who would be on that team. I won't reveal all the names -- and some have changed in between drafts, by the way -- but one character who has always been in this new team is Captain Marvel."
