When Captain America: Civil War hits theaters in just four short days, it will not only kick off Marvel Phase 3, but it will also introduce the new Spider-Man, played by Tom Holland. The actor will go on to star in a new standalone adventure, which was recently titled Spider-Man: Homecoming, set for release on July 7, 2017. We learned in a recent trailer for Captain America: Civil War that Spidey will be fighting alongside Tony Stark in Team Iron Man, and last month, it was confirmed that Robert Downey Jr. will return as Iron Man in Homecoming. Today we have new details about Spider-Man and Iron Man's developing relationship, courtesy of a new interview with Captain America: Civil War directors Anthony Russo and Joe Russo.

Last month during CinemaCon, exhibitors were shown a scene from Captain America: Civil War, where Peter Parker comes home to find Tony Stark sitting on his couch with Aunt May (Marisa Tomei). Tony discusses a "grant" proposal with young Peter. The directors spoke with IGN about the Spider-Man/Iron Man dynamic and how it will evolve in future movies. Asked if the friendship will be an ongoing part of the MCU, this is what they had to say.

"Absolutely. I think Downey is officially signed on now to Spider-Man: Homecoming, and I think that's what so fun about it. That's what's different in terms of this interpretation of Spider-Man. Two things: one, is that we cast an actor who is very close in age to a high schooler. Tom is really the first young actor to portray the part, and he has an incredible vulnerability and a certain confidence married together that create this very youthful and exciting character. Two, the other thing that's compelling is he's now in the Marvel Cinematic Universe, and he can interact with the characters in that universe. I think that this mentor relationship that Tony has developed with Peter Parker is probably one of the most interesting things the universe has moving forward."

In Marvel's Civil War, Steve Rogers leads a newly formed team of Avengers in their continued efforts to safeguard humanity. The action is set in the aftermath of Avengers: Age of Ultron. Following another incident involving the Avengers that results in collateral damage, political pressure mounts to install a system of accountability, headed by a governing body to oversee and direct the team. The new status quo fractures the Avengers, resulting in two camps, one led by Steve Rogers and his desire for the Avengers to remain free to defend humanity without government interference, and the other following Tony Stark's surprising decision to support government oversight and accountability.

Team Iron Man includes Tony Stark (Robert Downey Jr.), Black Widow (Scarlett Johansson), Vision (Paul Bettany), War Machine (Don Cheadle) and the new characters T'challa (Chadwick Boseman) and Spider-Man (Tom Holland). Team Cap includes Captain America (Chris Evans), The Falcon (Anthony Mackie), Scarlet Witch (Elizabeth Olsen), Hawkeye (Jeremy Renner), Ant-Man (Paul Rudd) and The Winter Soldier (Sebastian Stan). Captain America: Civil War also stars Frank Grillo as Crossbones and William Hurt, reprising his role from The Incredible Hulk as Thaddeus Ross.
