Hollywood loves an established fan-base, and that's exactly what the 9 million people who bought best-seller "Eat, Pray, Love" are - a solid base.
If each of them — mostly women 30 and older — buys a ticket to the film starring Julia Roberts, that adds up to $72 million at the US box office.
Not bad for a chick flick.
The model is Sony's "Julie & Julia" which almost exactly a year ago generated $94 million at the US box office.
Plus, Sony/Columbia , releasing the film in 3,100 theaters this weekend, has invested in reaching younger viewers beyond the core middle-aged fans of the book. Sony's promoting aggressively on MTV's "Jersey Shore", radio stations, and on Amazon. Tracking shows that the promotional push is working with 20-somethings, and could even draw older teens.
