During a Q&A session while promoting The Avengers 2 Blu-Ray, Marvel Studios president and producer Kevin Feige tackled the subject of the new Spider-Man, who will be 15-years-old in the films and played by Tom Holland (via IGN).
Regarding the Spider-Man Sony deal, Feige offered:
Making that agreement ... was great, and was really amazing, and on a personal level making these movies, it means a lot because I think we can do great things with Spider-Man," Feige said. "I think Spider-man can serve great purpose in our universe and that's where he belongs. That was what was unique about him in the comics was not that he was the only superhero in the world; it's that he was a totally different kind of superhero when compared against all the other ones in the Marvel universe at the time.
Feige was also asked about Spider-Man showing up "late in the game," with Feige replying:
...it's not about when you show up, it's about what you do once you're there...
Feige also let it be known that Marvel has alternate plans set up if things don't go exactly as planed:
This has been a dream of ours for a long time. We always had contingency plans, which we always do anyway. Are we going to be able to make another deal with this actor? If so, we're going to do this; if not, we're going to do this. If we get the rights to a certain character, that's great; we're going to do this. If not, we're going to do this. We always sort of operate under those various alternate timelines available and ready to shift if something happens."
Feige also noted connecting Spider-Man to the rest of the MCU isn't their main priority.
...the most important thing as a standalone is relaunching Spider-Man in his own standalone movie with his own storylines that fits into this universe. That is job number one for us. ... The connectivity is great, but it doesn't drive the train.
Regarding Captain America: Civil War, Feige said the movie is "very much Cap's story" and it's "very much a sequel to the Winter Soldier.
Tom Holland will first be appearing in "Captain America: Civil War" followed by the 2017 Spider-Man reboot.
