In an interview on NBC's "Today" show, Pitt said: "Let me be very blunt: I hate them. I hate these people. I don't understand ... that they do that for a living."
Pitt said there should be laws against celebrity photographers who "climb over your walls wearing camouflage and calling out your kids' names as you're trying to take them to school."
The actor appeared Tuesday to talk about his humanitarian work in New Orleans, but the conversation turned to his famous family. Pitt said he doesn't like talking about Angelina Jolie and their six children.
Said Pitt: "It seems to get cheapened somehow as it goes through the filters and the airwaves - and some things you just want to keep close to the chest."
