The Oscar-winning actress and her children, four-year-old twins Hazel and Phinnaeus and son Henry, two, are staying in the town of Pataudi, near the capital Delhi, while Julia shoots new film Eat, Pray, Love.
Julia and husband Danny Moder are so worried about their family's safety they have employed hundreds of bodyguards, including police officers and snipers.
They are transported everywhere in bulletproof cars and helicopters patrol the skies 24 hours a day.
But Julia's extreme security regime has enraged locals, who have been banned from attending a Hindu temple when the star is filming there.
A police officer said: "Nobody can breach the cover. We have strict instructions."
The restrictions are particularly upsetting for locals as September is one of the holiest months in the Hindu calendar.
One worshipper said: "It's the holiest time of the year and we must not be stopped from visiting our own temple."
