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.

Back in 2014, the Marvel Cinematic Universe became the biggest movie franchise of all time, domestically, surpassing Warner Bros. Harry Potter franchise which earned $2.39 billion domestically ($7.7 billion worldwide) throughout its eight-movie run. The MCU has currently brought in a whopping $3.9 billion domestically, and it just passed the $10 billion mark worldwide, the first franchise ever to do so. We'll be sure to keep you posted if Captain America: Civil War ends up passing Deadpool on the domestic charts.

After Captain America 3 closes out its run, Phase Three will continue with Doctor Strange, which hits theaters on November 4. Next year, the MCU will debut Guardians of the Galxy 2 (May 5, 2017), Spider-Man: Homecoming (July 7, 2017) and Thor: Ragnarok (November 3, 2017), followed by Black Panther (February 16, 2018) ,Avengers: Infinity War Part 1 (May 4, 2018), Ant-Man and the Wasp (July 6, 2018), Captain Marvel (March 8, 2019) and Avengers: Infinity War Part 2 (May 3, 2019). The studio has also set three Marvel movies for release on May 1, July 10, and November 6 in 2020, which will kick off Phase 4.
