Ever since it was announced that Spider-Man was coming to the Marvel Cinematic Universe, questions have swirled about how closely connected the character and his films would be. The abundance of Tony Stark in the trailers has made it seem like Iron Man will be co-starring in Spidey's latest adventure, indicating a rather close relationship between the franchises However, that's not exactly the case.
Iron Man's role in the latest "Spider-Man" movie is certainly more than a cameo, but it's not exactly a "Marvel Team-Up" either. This is a "Spider-Man" story and Iron Man is taking a supporting role, with Robert Downy Jr. reportedly only having filmed "about five or six scenes" for the entire movie. According to Screen Rant, Tom Holland describes the relationship between the heroes as less a father/son feel, and more of the Avenger being a “big brother” figure to Spider-Man. “ I think Robert is more like a big brother than he is a father figure because he picks on him and he is down on him quite a lot. But then there is that level of him caring about him like his own, and Robert has really brought something lovely to the character. It’s a very different side of Stark than you’ve ever seen before."
This seems like a fitting development for Robert Downey Jr., who has now been in the MCU for a decade. After putting the young Peter Parker in huge amounts of danger in "Civil War," it wouldn't make sense for him to take on a father figure role; Tony Stark would make a very irresponsible dad, and the cool big brother role fits a lot better.
So again, "Homecoming" is not intended to be a full on duo movie, but Stark will definitely have a continuing presence. IT will probably be similar to what readers saw in the J. Michael Straczynski era of the "Spider-Man" comics, where in the lead up to "Civil War," Peter Parker went to work for Tony Stark, was the recipient of a bunch of cool gadgets, and learned a lot from the (slightly) older super-hero.
Directed by Jon Watts (“Clown”), written by John Francis Daley and Jonathan M. Goldstein (“Vacation”), and starring Tom Holland, Michael Keaton, Marisa Tomei, Robert Downey Jr., Zendaya, Donald Glover, and many, many others, “Spider-Man: Homecoming” swings into theaters on July 7, 2017.
