Marvel has unveiled a new trailer for "Avengers: Age of Ultron," which comes out May 11.

Robert Downey, Jr., Samuel L. Jackson, Chris Hemsworth, Mark Ruffalo, Cobie Smulders and more are featured in the sequel that is sure to be action-packed.

The movie will feature an all-star cast of Marvel Heros including Iron Man, Thor, The Hulk, Captain America, Black Widow, Hawkeye, Quicksilver and Vision.

Samuel L. Jackson will play Nick Fury. Fury was the former director of S.H.I.E.L.D. and originally recruited the Avengers.

Smulders, who got most of her fame from the show "How I Met Your Mother," will star as Maria Hill. Hill was a former S.H.I.E.L.D. higher-up. Now, she works for Tony Stark (Iron Man).

With a $250,000,000 budget, "Age of Ultron" surely will need a good opening week at the box office.

Filming has taken place in some exotic locations. England, South Korea, Bangladesh, South Africa, and Italy have all been places where scenes from the movie have been shot.

The movie has been filmed since February of 2014 and it commenced in August.

More Marvel movies are already set for the future. In this movie though, many are predicting that a major character could very well die.

Screencrush.com is predicting that someone will die and even includes odds on which character will. Hawkeye has the best odds of dying at 10-1 and Captain America has the lowest odds at 10,000-1.

Marvel is going to make an "Iron Man 4," so Iron Man dying is probaby not going to happen.
