Ben Affleck Dressed as Batman at Son Samuel's Birthday Party

Ben Affleck heads to a studio for a day of work on Friday (March 4) in Santa Monica, Calif.

The 43-year-old actor recently dressed up as Batman, the same superhero he plays in Batman v Superman: Dawn of Justice, for his son Samuel‘s 4th birthday party.

“We all dressed up, I dressed up as a ninja, and Ben dressed up as Batman for Sam, which was the best dad moment in history,” Jennifer told Extra. “It was pretty sweet.”

“He wanted a superhero birthday party and so he wanted superheroes there,” Ben said while on Jimmy Kimmel Live. “He was like, ‘and I want you to do Batman. Real Batman!’”

“There was Wonder Woman, Captain America, Iron Man and there was me … it was so mortifying,” Ben added. “First I thought, ‘It’s kids. It’s kids.’ I didn’t think that, of course, like, all their parents are there. So I had to, like, put on my outfit for this movie, and put on my scary face for the 4-year-olds and all their folks are there. It’s 11 in the morning and they’re kind of like ‘Wow. Batman.’”
