Yesterday, we reported that Marvel's first Phase 3 adventure Captain America: Civil War has become the biggest movie of the year at the worldwide box office, passing Zootopia's $971.1 million tally with $981.9 million. Most expected this superhero movie wouldn't take long to surpass the $1 billion mark worldwide, and they were right, with the Marvel adventure crossing this milestone today. The movie has earned $314 million domestically through Thursday, its 14th day in North American theaters, and an additional $677 million internationally after 23 days in release around the globe.

Variety reports that the movie has become just the 25th in history to surpass $1 billion worldwide, and the fourth in the MCU to achieve this landmark. 2012's The Avengers remains the studio's highest grossing movie, both domestically ($626.6 million) and worldwide ($1.5 billion), followed by Avengers: Age of Ultron ($459 million domestic, $1.4 billion worldwide) and Iron Man 3 ($409 million domestic, $1.2 billion worldwide). Captain America: Civil War will likely pass Iron Man ($318.4 million) and Guardians of the Galaxy ($333.1 million) soon to become the fourth highest-grossing movie domestically in the MCU.

While Marvel's Civil War is the first movie of 2016 to cross $1 billion, it still has some work to do in order to surpass Deadpool as the highest grossing movie domestically this year. Deadpool currently holds the top spot with $362.5 million, followed by Zootopia ($332.1 million), Batman v Superman: Dawn of Justice ($328.3 million) and The Jungle Book ($315.2 million). With Cap entering just its third week in theaters this weekend, it seems likely that it could surpass all of these movies to become the biggest of 2016, to date.
