Joker has become the most profitable comic book movie of all time, having made more than $950 million at the worldwide box office.

It tells the story of how Arthur Fleck (played by Joaquin Phoenix) becomes the Joker, Batman's nemesis and one of the most infamous comic book villains ever.

Forbes reports Joker has now made more than 15 times what it cost to make.

Director Todd Phillips made the movie on a budget of $62.5 million a fraction of the budget of many comic book adaptations.

Avengers: Endgame, the highest-grossing movie of all time, has earned close to $2.8 billion but had a budget of $356 million.

Endgame has made more at the box office overall, but Joker has made more in relation to what was spent to make it.
