The movie is also the highest rated R rating movie in the US beating out 2018's Deadpool 2.
The feat in the UK is a little more impressing as the previous highest grossing 15 certificate movie was The Full Monty from 1997, so the record was 22 years old.
Joker has so far made over £50 Million in the UK, and as the film is still at number 1, and looking at the new release schedule it could spend a 6th weekend at the top, the film total UK gross is set to grow even more.
