The two are in the capital city shooting The Monuments Men, with George Clooney, though on Sunday’s day off, Damon and wife Luciana did what the parents of 500 other kids did in Berlin: took them to Jack’s Fun World for some indoor fun and games.
The owner of the park, Oleg Nepomnjascij, tells PEOPLE that the Damons were impressively easygoing. “I take my hat off to him,” he said.
To the delight of the other parents, the star and his family just hung out like everybody else, while their kids – Alexia, Isabella, Gia and Stella – ran and jumped and bounced and shrieked for joy.
Meanwhile, Blanchett and her family braved the cold outside. With temperatures down to 12 degrees, she and her mother June took the actress’s three boys – Ignatius, Dashiell and Roman – out for some serious sledding.
So icy were conditions in Volkspark Friedrichshain that Blanchett crashed the sled into a snow bank, according to the German publication Bild, though no one was the worse for wear – and they all laughed a lot.
