Affleck, who plays Batman, said that the assembly of several well-known superheroes in the new movie will make for an interesting watch.
“Justice League is a big change tonally,” he told Geek Week, “because you now have the personalities of all these different characters coming together and it gives you a chance to infuse a lot of humour into the scenes.
“For Bruce, he’s having to open up and play well with other because he knows he needs them, so while he doesn’t lose sight of how serious the threat is, he’s humanised by the Flash’s earnestness, Diana’s warmth, even Aquaman’s needling.”
Gal Gadot, too, spoke of the humour that fans can look forward to.
“The goal of the team is intense – they have to save the world, after all,” she said.
“But the humour that comes into it from all of these characters trying to work together, some of them with more experience, some with essentially none, results in a lot of laughter and playful banter that I believe audiences will really enjoy.”
The DCEU is on a high right now, after Wonder Woman reversed its fortunes earlier in the year.
The summer smash broke records and more than made up for the lukewarm receptions received by Batman V Superman and Suicide Squad.
The film is one of several new releases for the studio on the horizon.
It’ll be followed by Aquaman on December 21, 2018; while Wonder Woman 2 is expected on December 13, 2019 – when it will face Star Wars 9.
Justice League is out on November 17.
