1. Iron Man & Spider-Man
Following the disappointing Amazing Spider-Man 2, Marvel Studios has the odds stacked against them when it comes to reigniting interest in the iconic wall-crawler. While his appearance in Captain America: Civil War next year is sure to help, yet another reboot featuring the character could prove to be a tough sell, so why not throw the most popular Avenger in there to generate significantly more interest?
Before the events of Civil War, Peter Parker and Tony Stark developed a close bond thanks to their love of science and teamed up on a number of occasions, and having Iron Man show up as a mentor of sorts to the young superhero would make for an interesting dynamic to explore on the big screen.
