Now it appears that they will, as EW reports that Marvel head honcho told them that while it will be a Sony movie, other Marvel characters are likely to appear too. He says, “[Spider-Man] is in the universe now, and the fun of the universe is that characters go back and forth.”
However, there’s no news on what characters might show up.
Bringing Spider-man into the Marvel universe seems to be paying off, as in early reports from critics screenings of Civil War, Tom Holland’s take on the web-slinger has come in for particular praise. He’ll also play the character in the stand-alone film, planned for 2017, with Marisa Tomei as Aunt May. Jon Watts will direct.
