Justice League (out November 17)

Even superheroes need backup. With the emergence of a new powerful enemy (the immortal, hand-to-hand combat expert Steppenwolf), Batman (Ben Affleck) and Wonder Woman (Gal Gadot) must enlist a team of metahumans — including Aquaman (Jason Momoa) and The Flash (Ezra Miller) — to save the world once more. Explains Gadot of the hotly anticipated comic book flick, “Some of the biggest icons in the whole DC universe come together to fight for the first time.” The Israeli actress and Boston-born Affleck jump into action with Us.

Us Weekly: How have your characters changed since we last saw them?

Gal Gadot: She’s grown up — it’s been a century, after all! She’ll bring her specific qualities to a group dynamic, and she understands the enemy better than anyone else.

Ben Affleck: In Batman v Superman, he was at the end of his rope. But in Justice League he’s finding hope again. He has to open up and play well with others. He knows he needs them.

Us: Ben, does Batman struggle to fit in?

BA: He’s sort of the ultimate loner, but he’s really trying to make it work and develop a good relationship with all of them. He might be a mentor to The Flash.

Us: What’s the dynamic between Batman and Wonder Woman?

GG: Since they’ve fought together, they know each other’s strengths. They also understand the hope Superman stood for, that was lost [when he died], so they feel that more than the others.

Us: Physically, how did you prep?

BA: It’s all about paying attention to what you eat, lifting weights, cardio sessions. The batsuit is really form-fitting, so you have to prepare!
