'Avengers 2' is coming! And, if you're reading this, chances are strong that you are one of the many people who made 'The Avengers' one of the biggest hits of all time and you're as excited as we are for the sequel, 'Age of Ultron.' With 'Guardians of the Galaxy' behind us, there's no more Marvel movies to tide us over until 'Avengers 2' hits theaters, and there's nothing quite like seeing all of the Avengers together in one movie, kicking ass and saving the world as modern cinema's biggest and craziest superhero team.

To help make the wait seem not quite so long, you can whet your appetite for more epic superhero action by going over everything we know about 'The Avengers: Age of Ultron' at the moment.

When Will 'Avengers 2' Open in Theaters?


'Avengers 2' will open in theaters on May 1, 2015, putting it in position to start the summer off with a bang ... in about two years. It's certainly not a randomly selected date, either. The first 'Avengers' film smashed box office records when it opened on May 4, 2012, and 'Iron Man 3' broke the bank with its May 3, 2013 release. At this rate, Marvel and Disney look poised to set the summer movie bar high every year for the foreseeable future.

What is the "Age of Ultron," Anyway?


In the Marvel comics, Ultron is an aggressive, villainous A.I. housed inside the body of a killer robot. He's highly intelligent and has a bone to pick with the Avengers, who are responsible for his creation and his multiple defeats. Being a robot, he's able to repair himself following every encounter with Earth's mightiest heroes, becoming stronger and tougher every time he shows up. Although certainly not known too well by casual fans, Ultron has been a staple of the comics for decades now and one of the greatest recurring Avengers villains.

In the comics, Ultron is the creation of Hank Pym (aka Ant-Man), but the film will retool his origins, with early buzz suggesting that Tony Stark will be responsible in the Marvel movie universe. However, Marvel stated that 'Captain America: The Winter Soldier' has the most tie-in with the events of 'Avengers 2,' and that film saw an algorithm used to predict which individuals could become a threat to the villainous Hydra organization, and 'Captain America' villain Dr. Zola (Toby Jones) returned as an A.I., his consciousness having been uploaded to a computer. Could Ultron arise as of result of this technology?

Ultron is set to be played by the great James Spader, who will bring the villain to life via motion capture and his amazing, icy voice. Although he remains mum on the details, Joss Whedon promises an interesting take on the character, saying, "He’s not a happy guy, which means he’s an interesting guy."

For a more complete look at Ultron, we've got you covered.

Which Avengers Are Returning?


Every major actor from the first film (minus Clark Gregg as Agent Phil Coulson) will be back for the sequel.

After some aggressive (and very public) negotiations, Robert Downey Jr. signed on to reprise his role as Tony Stark/Iron Man, earning a monstrous paycheck in the process. One-by-one, the rest of the cast was confirmed, with Chris Evans (Steve Rogers/Captain America), Scarlett Johansson (Natasha Romanov/Black Widow), Chris Hemsworth (Thor), Mark Ruffalo (Bruce Banner/The Hulk), Jeremy Renner (Clint Barton/Hawkeye) and Samuel L. Jackson (Nick Fury) returning to the fold. In fact, the only major characters not returning from the first film seems to be Tom Hiddleston's villainous Loki and Gwyneth Paltrow's Pepper Potts. While he didn't appear in the first 'Avengers,' it looks as if Don Cheadle will bring his Rhodey/War Machine character to the sequel, as well. Behind the camera, Joss Whedon is once again writing and directing.

So, in short, it's the same folks responsible for the first one. You know what they say about fixing things that aren't broken.

Early in the process of developing 'Avengers 2,' it was revealed that the characters of Quicksilver and Scarlet Witch were being added to the film's superhero line-up. Although "mutants" in the Marvel comic book universe (and the children of X-Men villain Magneto!), this brother/sister duo receive their powers through Hydra member Baron von Strucker's experimentation with the super-soldier serum (as seen during the post-credits scene of 'Captain America: The Winter Soldier'), and are aligned with Hydra in the beginning of the film.

The role of Quicksilver, whose powers include super-speed, has recently been filled by 'Kick-Ass' star Aaron Taylor-Johnson, while the reality-altering Scarlet Witch will be played by the very talented and on-the-rise Elizabeth Olsen, and NBC's 'Dracula' star Thomas Kretschmann takes the villainous role of Strucker.

In addition to the superhero siblings, Paul Bettany, who previously voiced JARVIS in the 'Iron Man' films, has signed on to play Vision, the humanoid created by Ultron to help battle the 'Avengers.' Ms. Marvel has also been confirmed to be making an appearance in the film although her role has yet to be cast.
