Angelina Jolie and Brad Pitt are planning to retire from the movie industry in a few years to dedicate their time to raising their children. The Hollywood superstars have four children, three of whom are adopted, Cambodia-born Maddox, Vietnam-born Pax and Ethiopia-born Zahara, and biological daughter Shiloh - and plan on having more. Jolie says, "I think both of us only plan to work for a few more years. "Brad and I have a lot of kids. And we want to have more kids, and they demand a lot of time. "You can't balance everything."
