2. Avengers: Age of Ultron
The sequel to the Avengers was expected to be even bigger, but because of the reviews it got, it earned a little less, but still a huge Box office number. Age of Ultron grossed $1.4 Billion worldwide at a production budget of $250 Million.
The sequel to the original ‘The Avengers’ is a great addition to the roster of MCU movies, but lacked depth and emotional punch of the first one.
