The actor is expected to shoot battle sequences for zombie drama World War Z in Falmouth. According to The Sun, the family have opted to stay on a yacht, instead of one of the local hotels.
"Brad thought the family might as well have a holiday while he's shooting World War Z. Cornwall is a little different from their usual destinations but they've heard lots of good things about the county," said a source.
"Staying on a yacht will mean they'll be able to visit various seaside towns so the kids won't get bored."
The insider added: "They're all really looking forward to it."
After filming on the Cornish coast, Pitt will relocate to Glasgow to film more scenes later next month.
The movie, based on Max Brooks's World War Z: An Oral History Of The Zombie War, is expected to be released next year.
