It was rumored last week when the Civil War cast was doing press for that movie, but now it’s official. Robert Downey Jr. is in the cast of Spider-Man: Homecoming.
In Captain America: Civil War, Tony Stark recruits Peter Parker to Team Iron Man and even gives Spider-Man his famous costume. He’s also the only person who knows Peter’s secret. So putting him in Homecoming makes sense, as it’s likely Stark is going to become something of a mentor of Peter.
This will definitely give Spider-Man: Homecoming a big box office boost and help the reboot even more than it being set in the MCU will.
