Russell Crowe is starring in the reboot of The Mummy franchise alongside Tom Cruise and that's angered Nicole Kidman, according to a new report.

Kidman was born 20 June 1967 in Honolulu, Hawaii, while her Australian parents were temporarily in the United States on educational visas.
Her father was Antony Kidman (1938–2014), a biochemist, clinical psychologist and author, who died of a heart attack in Singapore aged 75.
