He played a half-human, half-demon in the WB supernatural series “Charmed” and a playboy plastic surgeon in the FX series “Nip/Tuck.”

Actor Julian McMahon, best known for his roles in "Nip/Tuck" and "Fantastic Four," has died at age 56 after a "valiant" battle with cancer.

McMahon was born in the 1960s, into the highest portions of the Australian upper crust: His father, Sir Billy McMahon, served as the country’s Prime Minister from 1971 to 1972, and his mother, Lady Sonia McMahon was a prominent (and infamously intimidating) socialite and philanthropist.
