However, the film’s director, Todd Phillips, admits that he was initially unsure of Joaquin’s participation in the movie. 

Todd explained: ‘If you took two pages of our script and you [hold it up] to our scene, you realize how an additive an actor can be. 

‘It was a pursuit to get him because initially it feels like, “ugh, comic book movie.”

‘Just the idea of it is something he wasn’t so keen on pursuing, and even when I would explain to him it’s not that, it kind of says that, but really we’re doing this other thing, there was a little resistance.

‘But the more I got to know him, the more I hung out with him, and we spent a lot of time talking about what the movie will look and feel like, and then one day he magically showed up. He never said yes. 

‘He just one day showed up to a wardrobe fitting. It was an incredible partnership.’
