Cate Blanchett's JFK conspiracy thriller Blackbird, due to start filming in Australia in January, has moved offshore.
Writer-director David Mamet, who visited Sydney last week to scout locations, has decided to relocate the shoot to the US, according to Inside Film magazine.
The news comes just weeks after Blanchett confirmed the project had been green lit.
"We've been talking for a couple of years about doing this, so I'm thrilled it's actually happening,'' she said in Sydney during an interview to promote the Woody Allen film Blue Jasmine, for which she is a hot favourite for an Oscar nomination.
"(Mamet) wouldn't be coming here if the crews weren't magnificent.''
Blanchett landed her first major stage role opposite Geoffrey Rush in the acclaimed 1992 Sydney Theatre production of Mamet's Oleanna, for which she won a critics award for best newcomer.
Blackbird would have been the first feature the 44-year-old actor had shot in Australia since Cabramatta crime drama Little Fish, with Sam Neill and Hugo Weaving, in 2005.
The harbour city would have doubled as Los Angeles in the film.
Penned by the Pulitzer Prize-winning playwright-turned filmmaker, it's the story of woman who discovers some dark family secrets when she attends the funeral of her grandfather, a Hollywood visual effects artist who moonlighted for US special ops agencies
Two other high profile international projects, however, are still due to start filming in the coming months.
Angelina Jolie's drama Unbroken, starring Jack O'Connell as US Olympic athlete Louis Zamperini, rolls out on October 21, according to IF.
And the Kate Winslet and Judy Davis tragicomedy The Dressmaker begins production in rural Victoria early next year.
Set in the outback in the 1950s and billed as a gothic tale of love, hate and haute couture, it will be directed by Jocelyn Moorhouse (Proof).
