SUPER: The Marvel Cinematic Universe that we see in theaters today is much bigger than the one we first saw with The Avengers. There are many more heroes and there are new pieces being added with the ABC TV series and the Netflix series. How do you organize it? Is there a chance we see Jessica Jones battling Thanos (the villain) in Infinity War?
Anthony Russo: It's complicated. When we start to serialize the telling of stories it's difficult. You have to have a lot of control and focus on the course of history. The films are controlled by a group led by Kevin Feige, so they function as a unit. Other products, even if they are from Marvel, are controlled by others. Then there is the possibility of a crossover, but it's more complicated. It is a smaller scale version of the problem that exists when remembering that Fox holds the rights to some of Marvel's most popular characters, as does Sony and others. As storytellers, we only have control over what happens in Marvel movies, but everything is possible, Spider-Man (whose rights were held by Sony) became possible!

So not impossible, but complicated. Hmm...
