Here's a twist. It seems the Spider-Man: Homecoming footage shown at CinemaCon featured Tony Stark upbraiding Tom Holland's Spider-Man for being reckless and destructive (Captain America and Nick Fury would certainly get a kick out of seeing Tony lecturing someone about that!).
Taking the stage were Marvel Studios president Kevin Feige, actor Tom Holland, director Jon Watts, Homecoming producer and former Sony chief Amy Pascall and her successor, Tom Rothman.
According to Feige, the idea for how to introduce Spider-Man into the MCU is to play up the fact that Peter Parker's been there the whole time, as he would've been roughly five or six at the time that Tony Stark revealed himself as Iron Man. Perhaps we'll get a few scenes of a young Peter Parker reacting and watching some of the more notable MCU events such as Hulk's Harlem battle with Abomination and the Chitauri invasion?
One development of note is that a mistake by Spidey during a ferry rescue scene prompts Iron Man to show up and make the actual save. Peter's struggle prompts Tony to take the Spider-Man costume/armor back as he tells Peter he "shouldn't need it to be Spider-Man." As such, Peter suits back up in the homemade costume briefly seen in Captain America: Civil War. This is another interesting development as it opens the door for Peter to potentially make his own costume by the film's end. It seems Watts wants to show Peter yearning to be an Avenger and operate on a larger scale but his journey in Homecoming will be about him learning to just take care of NYC. At one point, Tony literally tells him, "Can’t you just be a friendly, neighborhood Spider-Man?"
As previously disclosed, expect a new trailer for Spider-Man: Homecoming to make its way online later today. The film arrives in theaters on July 07, 2017.
