Black Phone 2 Worldwide Box Office: Ethan Hawke’s Horror Flick Set To Surpass 1990s Slasher Hit I Know What You Did Last Summer

After completing four weeks in theaters, Black Phone 2 has grossed $123.3 million globally, making it one of the most successful horror movies of 2025.

Black Phone 2 is also the sixth horror film of 2025 to gross over $100 million worldwide. While it remains to be seen whether it can break into the top 25 titles of the year, the horror hit is on track to outgross the popular 1997 slasher hit, I Know What You Did Last Summer. Read on to find out how much Black Phone 2 needs to earn to surpass it at the global box office.
