KATIE Holmes is about to start filming her new movie, Don't Be Afraid Of The Dark, but some questions from the crew will not be allowed.
The Batman Begins actor will begin filming on the closed Docklands set this week, as she, husband Tom Cruise and daughter Suri continue to explore Melbourne's sights and stores.
One film source from the set said that each crew member had signed agreements saying they would not ask the superstar about her religion, Scientology.
The couple, who have braved chilly weather to explore the city and have happily chatted to locals, are notoriously private when it comes to questions or discussions about their religion.
Holmes has never publicly addressed converting to Scientology since she started dating Cruise in early 2005.
The famous family was entertained late on Friday night for Cruise's 47th birthday celebration by singer Kate Ceberano, a fellow Scientologist who has known the couple for years.
Good friend and Crown casino owner James Packer also attended.
Cruise and Holmes are staying at the luxury Crown penthouse after searching Melbourne for appropriate accommodation, including some Toorak mansions.
Crown staff remain tight-lipped about the exact details of the star couple's stay, most likely at the direction of Packer, who has taken a personal interest in their time in Australia.
But Holmes and Cruise have taken advantage of some of Crown's shops, with Burberry reportedly closing its doors during the week to let Holmes go on a shopping spree.
Reports suggested the actor spent $50,000 on an alligator skin handbag, as part of an $85,000 bill, but staff would not discuss any details.
However, a spokesperson did confirm the store does stock an alligator skin handbag worth $50,000 - a favourite with wealthy VIP customers - which is locked away in a private safe.
Cruise was a vocal supporter in the Crown box at the Collingwood-Essendon game at the MCG on Friday night before his party, while his wife appeared less interested in what would be a foreign game.
The Valkyrie actor is no stranger to football - while married to Nicole Kidman in the 1990s, he went to see the Sydney Swans.
It is believed Cruise will not be in Melbourne for the entirety of his wife's movie shoot.
