Scarlet Witch and Quicksilver are two the exciting new character additions to Avengers: Age of Ultron, and the super-powered siblings are welcomed into the fold in this brand new trailer.
Elizabeth Olsen and Aaron Taylor-Johnson have reunited - they worked together last year on Godzilla - and will play mutant siblings this time around.
We got to see these characters briefly at the end of Captain America: The Winter Solider and I really am looking forward to seeing them in action when Age of Ultron hits the big screen next month.
A brand new teaser trailer for the first has been released, and saw shows all of out Avengers heroes strutting their stuff. It really is going to be an action packed ride:
Age of Ultron is already one of these most anticipated films of 2015, and really does look set to be the biggest Marvel film yet.
Over the years, Marvel have boasted some impressive cast lists, but I think that this is going to top them all. Robert Downey Jr, Chris Evans, Scarlett Johansson, Chris Hemsworth, Jeremy Renner, Mark Rufflo, Samuel L. Jackson, James Spader, Paul Bettany, Cobie Smulders, Idris Elba, and Tom Hiddleston are all on board.
When Tony Stark tries to jumpstart a dormant peacekeeping program, things go awry and Earth's Mightiest Heroes, including Iron Man, Captain America, Thor, The Incredible Hulk, Black Widow and Hawkeye, are put to the ultimate test as the fate of the planet hangs in the balance.
As the villainous Ultron emerges, it is up to The Avengers to stop him from enacting his terrible plans, and soon uneasy alliances and unexpected action pave the way for an epic and unique global adventure.
We are counting down the days until Avengers: Age of Ultron hits the big screen and it looks like it really isn't going to disappoint.
Avengers: Age of Ultron is released 23rd April.
