According to Box Office Mojo, “Avengers: Age of Ultron ruled the box office this weekend with a huge $187.7 million, which is the second-biggest debut ever. Unfortunately, the top opening ever belongs to its predecessor, Marvel’s The Avengers ($207.4 million)” which is a great start, of course, and continues to augur well for the future of the MCU.
The site also noted that “the Avengers sequel also continues to do strong business overseas, where it’s earned $439 million before even debuting in China or Japan”. Which hopefully means that the movie will go on to outgross Transformers: Age of Extinction.
