Spider-Man’s confirmed inclusion in 2016’s Captain America: Civil War has taken some of the limelight away from Marvel’s upcoming super-team epic Avengers: Age of Ultron, but the studio is doing its best to keep viewers excited for this summer. The official poster for the May 1 release debuted online on Tuesday, giving fans a slight glimpse of a new Avenger and revealing some surprising casting details for the film.

Chris Evans’ Captain America, Robert Downey Jr.’s Iron Man, Chris Hemsworth’s Thor and The Hulk are unsurprisingly front-and-center in the poster, with Jeremy Renner’s Hawkeye and Scarlett Johansson’s Black Widow yet again cast to the side. Samuel L. Jackson’s Nick Fury and new Avenger additions Scarlet Witch and Quicksilver also make an appearance in the poster, ready to fight the army of Ultrons swirling around the Earth’s Mightiest Heroes.

If the two official trailers for the film didn’t make it clear, the poster proves that Tony Stark’s attempt to create an artificially intelligent peace-keeping army will go horribly awry. James Spader’s performance capture robot will seemingly be trying to wipe out the entire human race, starting with the Avengers. The poster does give fans something new to get excited over, as the credits on the bottom reveal that Anthony Mackie’s The Falcon, Idris Elba’s Heimdall, Stellan Skarsgård’s Dr. Eric Selvig and Hayley Atwell’s Peggy Carter will all appear in the film. Atwell’s scene will likely be a flashback, since Captain America: The Winter Soldier showed that the former S.H.I.E.L.D. agent is now an elderly woman in a nursing home.

The poster also gives viewers their first glimpse of a new robotic Avenger, Vision, who will be played by Paul Bettany. The character is obscured by a bright light, but with director Joss Whedon’s love for secrecy, it will likely be the best fans will get until May 1.
