When Variety broke the news that Marisa Tomei would play Aunt May in the Marvel-Sony Spider-Man reboot they reported added that she probably wouldn't appear in Captain America: Civil War, but The Hollywood Reporter is reporting differently on that matter.
Contrary to other reports, THR hears that Tomei's Aunt May may be making her first appearance in Marvel and Disney's Captain America: Civil War.
That makes sense. Why else would Marvel lockdown 'Aunt May' this early? Seems to indicate to me that Marisa Tomei will be needed for a quick cameo in Captain America: Civil War, but I could be wrong. It happens. Either way, we'll her and Tom Holland's Spider-Man/Peter Parker get their proper introduction in Jon Watts' solo Spider-Man movie, which arrives July 28, 2017.
Captain America: Civil War picks up where Avengers: Age of Ultron left off, as Steve Rogers leads the new team of Avengers in their continued efforts to safeguard humanity. After another international incident involving the Avengers results in collateral damage, political pressure mounts to install a system of accountability and a governing body to determine when to enlist the services of the team. The new status quo fractures the Avengers while they try to protect the world from a new and nefarious villain.
Captain America: Civil War opens in theaters May 6, 2016.
