Now that’s just something everyone should know how to do.

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.”
