Spider-Man is just four weeks out from his Marvel Cinematic Universe debut in Captain America: Civil War and today we’ve learned that he’ll be joined by some of his new friends in his next solo film, directed by Jon Watts (Cop Car). Marvel Studios President Kevin Feige confirmed that characters from the MCU will appear in the next Spider-Man film, telling Entertainment Weekly, “He is in the universe now, and the fun of the universe is that characters go back and forth.”

There is, of course, no word yet on which characters will join Spider-Man, but the list of suspects should start with the characters he will meet in Captain America: Civil War. He’s on a nickname basis with Tony Stark (Robert Downey, Jr.) in the latest Civil War trailer, so that’s one very expensive possibility. Alliances can change, though, so until we know which characters Spidey is aligned with at the end of the film, your guess is as good as mine.

Sony Pictures, the studio that owns the movie rights to Spider-Man, will be distributing the film, but it is still a Marvel Studios production. The two companies, and Marvel’s parent company, Disney, are working together and sharing Spider-Man so that each studio can benefit. Marvel gets to add Spider-Man to its shared universe while Sony gets a Spider-Man film made by the people who are the absolute best at making films with Marvel characters.

That Marvel Studios is willing to share some of its characters with Sony, even when Disney is not distributing. bodes well not just for the next Spider-Man movie, but also the future of the Marvel Cinematic Universe. When the deal between Sony and Marvel was announced last year, the only films mentioned were the solo Spider-Man film and one Marvel Studios feature, which we now know is Captain America: Civil War. This new confirmation of collaboration suggests we will see Spider-Man in other Marvel Studios’ pictures for Disney, including one or both installments of Avengers: Infinity War.

Feige has previously said that all the necessary deals were signed for every character Marvel wants to include in Avengers: Infinity War (outside of roles yet to be cast). It’s looking more and more like Spider-Man is indeed part of that equation.

Spider-Man will officially arrive in the Marvel Cinematic Universe when Captain America: Civil War opens on May 6.
