8. Iron Man & The Hulk

IM&H

Much to the surprise of many fans, it was Robert Downey Jr.’s Tony Stark and Mark Ruffalo’s Bruce Banner who had the biggest “bromance” in Avengers Assemble. Last seen taking off in a car together, the two would briefly reunite for Iron Man 3’s after-credits scene before assembling with the rest of their teammates for 2015’s The Avengers: Age of Ultron. As of right now, The Hulk (who was played by Ed Norton in The Incredible Hulk back in 2008) is the only character whose movie hasn’t been granted a sequel by Marvel Studios, and while there has been talk of the Green Goliath getting another chance, we’ve heard nothing definite. So, why not pair Banner and Stark up for their own team-up adventure?
