The Batmen coincidentally ran into each other as they were shopping for costumes for their sons - Batman costumes, of course - in Los Angeles last Halloween.

'There he and I are standing in the Batman costume row and I said, "Do you have any tips?", Affleck recalled.

'And he said, "Make sure you can p*ss in that suit".'

Affleck also got a laugh when he revealed how directer Zack Snyder had pitched the character to him: 'He's at the end of his rope, he's older... he's like a burnout.'

As for the new suit, Snyder didn't mention if it had any new peeing capabilities, but he did shoot down rumours that the Kryptonite powered armour he can be seen wearing in the trailer made him more powerful. 

'It's not really enhancing his strength more than it is protecting him from Superman,' he revealed.

The two men also shed some light on the geography of the film: neither Batman's Gotham City or Superman's Metropolis have ever been given an exact location in the real world, but it's sort of been assumed they are both New York. 

For the film, they have been made neighbouring cities - similar to the Bay Area in California. 

The big rule we broke is we put Gotham and Metropolis next to each other,' Snyder confirmed. 'They're sister cities like Oakland and San Francisco.'

'There are some really interesting ideas of Metropolis being a big, successful city and Gotham being a place where a lot more downtrodden people live,' Affleck elaborated. 'There’s a ferry people take across who work in Gotham City.'

The amazing new trailer appears to confirm that this proximity is partially to blame for the rivalry between the two supposed good guys, as one of Bruce Wayne's buildings - and presumably many of the people that work there - being destroyed as collateral damage in a fight involving Superman.

The trailer also showed Gal Gadot in action as Wonder Woman for the first time.

'I feel like I have been given this huge opportunity to show the strong, beautiful side of women, finally,' she said during the during the Q&A session in Hall H. 'Wonder Woman has all the strength of a superhero but at the same time, she is very loving and sophisticated and has a lot of emotional intelligence.'
