Nicole Kidman is on the verge of severing ties with her stalled Australian movie "Eucalyptus" after entering into negotiations to play the role of photographer Diane Arbus in her tragic biopic "Fur".

The Australian actress was earlier awaiting a reworked schedule for "Eucalyptus", which was halted due to apparent script problems last month, reported the Internet Media Database.

But with the film also set to star Russell Crowe - which could delay the project - Kidman is now looking towards the Arbus biopic, where she's set to star with Robert Downey Jr.

British actress Samantha Morton was originally attached to the project on Arbus, who was known for her disturbing photographs but committed suicide in 1971.
