Oscar winner Nicole Kidman has been learning how to castrate young bulls for her new movie AUSTRALIA. The Baz Luhrmann-directed film will see Kidman play a 1930s English aristocrat who inherits a cattle station in the Outback and becomes involved with a cattle baron, played by Hugh Jackman. Kidman's role demands plenty of hands-on experience, including how to neuter the animals. She says, "I don't know if I'll have to do that, but it's best to be prepared."
