Affleck is playing Batman in the upcoming Zack Synder film Batman v. Superman: Dawn of Justice, and is in Detroit shooting the film. The A-list couple asked guests if their two-year-old son Samuel could hang out at the party, the Detroit Free Press reports. Obviously, guests welcomed the celebrities with open arms.
"I spoke with Ben for 10 or 15 minutes and he was very pleased with the facility. He was very interested in getting a Detroit Kid City out in L.A.," Garrett Dixon of Detroit Kid City told the publication. "He said they had a blast and will definitely be in contact with us."
This isn't the first celebrity family to hit up the kids venue. In 2013, Mark Wahlberg's kids went there while he was shooting Transformers: Age of Extinction.
