While the new Avengers film will not be hitting the big screens until the summer of 2015, many rumors, speculations, and spoilers are being released from various groups including fans, the production team, and even the actors themselves. The highly anticipated reassembly of the Avengers will be very different from its first installment, especially after the fall of SHIELD in "Captain America: The Winter Solider." Who the antagonist will be in the upcoming Marvel film is a no-brainer, having his name in the title. According to reports, Ultron will have three different versions throughout the movie, as the sentient robot seeks different materials to continue his upgrades.

Again, Iron Man steps up as the role of Tony Stark becomes more essential this time around in assembling the Avengers. He takes on the responsibility of ensuring global security and peace with his army of Iron Man drones. His Stark Tower will be converted into the Avengers Tower as well, where new costumes and technology will be funded. It will also house the new Quinjet.

To make the movie even more exciting, three new heroes will be added to the team, namely The Vision, who is confirmed to be played by Paul Bettany, Scarlet Witch and Quicksilver, who were both seen in the post credits clip of "Captain America." Quicksilver was also seen in the newly released X-Men film, "Days of the Future Past." However, they are portrayed differently by separate actors as the two Marvel universes do not intersect in theaters. While it's not the biggest news, several characters will be coming into the film sporting new costumes, such as The Hulk's new pair of pants. Probably the biggest spoiler is the news of Hawkeye getting killed in this film. This, however, is an unconfirmed speculation as a lot of things may still change before production is finally over.

For the time being, fans may enter the Marvel Cinematic Universe by visiting the exhibit in Times Square.
