"Unfortunately they are too smart for that and they require actually dressing up," Ben Affleck tells PEOPLE of his kids' high expectations for seeing Dad as Batman
Ben Affleck is bringing a version of his Batman character to TV — all for a good cause.
As part of NBC’s star-studded Red Nose Day Special, which benefits charities fighting child poverty around the world, the Oscar winner will appear as a “stripped-down” version of the famous DC superhero — the first time Affleck is doing so outside of the Batman v Superman and Justice League films.
“I’m doing my Batman voice,” Affleck tells PEOPLE about his involvement in the special. “No cowl — just the stripped-down, unplugged version.”
Might that be the same version that the father of three occasionally performs for his kids?
“Unfortunately they are too smart for that and they require actually dressing up to be impressed,” Affleck says with a laugh.
The actor admits that he enjoys being able to have a bit of fun with the character, since the Dark Knight is not particularly known for having a sense of humor.
“It’s a lot of fun,” says Affleck. “Batman is such a serious, heavy character, there is the temptation to be funny about it, or at least self-aware. I really enjoy it. Obviously it is a character that means a lot to a lot of people and I’m having fun playing it.”

Affleck was in the middle of playing the role in the upcoming film Justice League when he befriended Red Nose Day executive producer Richard Curtis. Affleck’s ex Jennifer Garner and their kids joined him in London, and the family rented Curtis’s house, “totally coincidentally,” Affleck says. “He made friends with Jennifer [Garner] and I, and it was a soft spot for me because we had the whole family in his house there in Notting Hill, which was really wonderful and beautiful. We had a great time and traveled throughout Europe from there as a base, so it was pure serendipitous good fortune.”
The Red Nose Day Special airs May 25 on NBC as part of a three-hour block of programming that begins with Celebrity Ninja Warrior for Red Nose Day at 8 p.m., followed by Running Wild with Bear Grylls for Red Nose Day featuring Julia Roberts at 9 p.m. and the Red Nose Day Special — with the U.S. premiere of the highly anticipated Love Actually mini-sequel — hosted by Chris Hardwick on NBC at 10 p.m.
