Marvel is developing a new Avengers film, currently known as "Avengers: Doomsday", which brings together characters from several previously separate franchises within its Marvel Cinematic Universe, including the Avengers, the Fantastic Four and the X-Men. This crossover approach follows years of Marvel building up individual hero stories in separate films, now converging into one larger narrative centred on the villain Doctor Doom.

At San Diego Comic-Con, an annual entertainment convention where studios showcase upcoming films to fans, Marvel held a panel in its largest venue, known as Hall H, to share footage and news about the project. Such panels are closely watched because they often provide the first public glimpses of casting and plot details for highly anticipated films, and fans frequently queue for long periods, sometimes overnight, to secure a seat.

Ryan Reynolds, known for playing Deadpool, and Hayley Atwell, known for playing Peggy Carter, are established performers within the Marvel franchise, so confirmation of their return signals how far the studio is drawing together its existing cast of characters for this project. The film's scale and the way Marvel manages this large ensemble matter to audiences and industry observers assessing the direction of the franchise going forward.
