"I think the girls are into it but my oldest daughter is a super Harry Potter nut so she's wanted me to be in that," Affleck told E! News' Maria Menounos earlier today while promoting Batman v Superman: Dawn of Justice alongside his co-star Henry Cavill. "I told her, 'I didn't have the option to be in a Harry Potter movie—this is what I got.'"
The Oscar winner thinks Violet, 10, and Seraphina, 7, will be more into Wonder Woman, played by Gal Gadot. "She's a cool role model for girls," Affleck said. "I didn't want to make a movie where the guys were the heroes and the women were the damsels in distress. [Wonder Woman] comes in and was more heroic than the both of us."
The Affleck kids have gotten used to being on movie sets.
"They've been on a million of Jen's sets and my sets," he said. "And we typically take them to the other's set and hang out…They've learned to really behave well on set and they're used to it, so they get it that we play other people and that's why we have a certain kind of life."
They don't always get to see the final product. "The last 10 years have been mostly R-rated movies so this is one they get to see," Affleck said.
However, Affleck will show Samuel an edited version that doesn't include the "scary" scenes.
What a dad!
Batman v Superman: Dawn of Justice is in theaters on March 25.
