Updated June 25: 20th Century Fox's Deadpool 2 has now become the third-largest R-rated film of all time with a $705 million global box office, according to Deadline. The Ryan Reynolds-starrer is trailing behind the original Deadpool ($783.1m) and The Matrix Reloaded ($742.1m), and has now passed It ($700.4m).
Breaking it down, Deadpool 2 has so far earned $304.1m domestically and $400.9m internationally.
Original Story: 20th Century Fox's Deadpool 2 earned $18.6 million at the domestic box office Thursday evening - breaking the record for R-rated films, according to The Hollywood Reporter.
That surpasses the previous record-holder, 2017's It ($13.5m), which took over the record from - you guessed it - 2016's Deadpool with $12.6m. The original Deadpool went on to make $132.4m in its 2016 domestic opening weekend.
