With Angelina Jolie
and Brad Pitt
as his parents, it's no surprise Maddox Jolie-Pitt has caught the acting bug.
On Monday, Pitt and the 11-year-old celebrated the U.S. premiere of World War Z
– Maddox makes a cameo in his dad's film as a zombie.
After Pitt walked the red carpet
, the pair attended the Samsung Galaxy-sponsored after-party at Catch restaurant, a Meatpacking district hotspot.
At the soiree, Pitt was visibly in a great mood. The actor held a drink in his hand, happily talked to everyone that approached him and posed for countless photos. He greeted actress and friend Catherine Keener with a hug and spoke to her for about 10 minutes. While Pitt interacted with executives, members of the media and fans, Maddox enjoyed the party in his own way – by hanging out with the the child stars of the film, Fabrizio Zacharee Guido, Sterling Jerins and Abigail Hargrove.
Playing a zombie game, Maddox and Guido spent the night together laughing and goofing off.
Later, when Chris Brown's "Look At Me Now" played, Maddox showed off another skill that might take him far in Hollywood – his dance moves!
