The 10 Most Massive Movies of the Decade — Broken Down by Year

The third installment of Tony Stark's story sees the beginning of what would eventually lead to civil war, as the movie challenges what it means to be a modern-day superhero and whether or not these heroes are truly hurting or helping. Following the success of The Avengers, Iron Man 3 included themes of loss and teams, which led the way for Marvel's Phase 2. The movie brought in over $1.2 billion dollars, making it the fifth-highest grossing film of all time, back in 2013.
