7. "Avengers: Age of Ultron" (2015)

Total gross revenue: $1,405,400,000

"Transformers," "The Dark Knight," and "Pirates of the Caribbean" are three franchises for which each has two movies in the billion-dollar club (you can add "The Avengers" to that list). The 2015 follow-up ensemble movie added James Spader as the terrifying new villain, and (surprising no one) "Age of Ultron" opened in the No. 1 spot around the world.
