Marvel Studios fed its rabid superhero fanbase a few very meaty appetizers for next year's highly anticipated "Avengers" sequel, "The Avenger: Age of Ultron," Tuesday (March 18).

"Avengers 2" isn't out until next summer, but the anticipation is already reaching a crescendo, especially with the first official member of the Avengers, Captain America, coming to movie screens for his own sequel, "Captain America: The Winter Soldier," on April 4.

Following the "Marvel Studios: Assembling a Universe" special on ABC, fans got a one-minute sneak peek of the film, followed by some incredible concept art via Twitter featuring the Incredible Hulk and Black Widow, who were played in the first installment by Mark Ruffalo and Scarlett Johansson, respectively.

More importantly, the first official images of new cast members Quicksilver (Aaron Taylor-Johnson) and twin sister Scarlet Witch (Elizabeth Olsen) were shown. In the artwork, Quicksilver, who possesses superhuman speed, is shown in his signature blue costume, running through a throng of bad guys.

Scarlet Witch, who possesses the ability to manipulate reality, has a more youthful appearance than comic book fans are used to and her costume is updated from an all-red ensemble to a more fashionable look of brown pants, white top and red leather jacket.

Production for the Josh Whedon-directed juggernaut began February 11, with the first two weeks of filming taking place in Johannesburg, South Africa.

"The Avengers: Age of Ultron" hits theaters on May 1, 2015.
