Despite being released nearly a year ago, Deadpool 2 continues to reel in money at the box office. Once Upon a Deadpool, the PG-13 edit of the film, recently made its big debut in China with a $21.4 million opening weekend, Variety reports.

This marks the first time a Deadpool film has been released in the China market, given the country's strict standards regarding explicit content in movies. Moreover, this added revenue has already proven noteworthy for 20th Century Fox's second Deadpool feature.

Combined with Once Upon a Deadpool's initial global launch, which brought in $7 million, this brings Deadpool 2's total worldwide box office gross to roughly $755 million. This means that it has officially surpassed 2014's X-Men: Days of Future Past, which topped out at $747.9 million.

This is a fairly significant milestone for a number of reasons. First and foremost, by passing Days of Future Past, Deadpool 2 has become the second-highest grossing film in the entire X-Men film series. What's more, the number one spot is still held by 2016's Deadpool with $783.1 million, meaning that the Merc With a Mouth is currently sitting at the top of the the list with not one, but two films.

Additionally, Days of Future Past currently holds a Certified Fresh rating of 90% on Rotten Tomatoes, making it one of the single-most critically-acclaimed films in Fox's X-Men franchise, second only to Logan with 93%. In turn, passing it at the box office is a fairly impressive notch in Deadpool 2's belt.

David Leitch’s Deadpool 2 stars Ryan Reynolds as the titular Deadpool, Morena Baccarin as Vanessa, T.J. Miller as Weasel, Leslie Uggams as Blind Al, Brianna Hildebrand as Negasonic Teenage Warhead, Stefan Kapičić as Colossus, Zazie Beetz as Domino, Julian Dennison as Russell and Josh Brolin as Cable.
