LOS ANGELES — Julian McMahon, an actor with dual Australian-American heritage famous for his work in “Nip/Tuck” and his portrayal of Dr. Doom in the “Fantastic Four” series, passed away on July 2 following a battle with cancer. He was 56 years old.

Kelly McMahon, his wife, verified his passing through a statement given to Deadline, noting he “passed away peacefully this week after bravely battling cancer.”

“Julian loved life. He loved his family. He loved his friends. He loved his work, and he loved his fans. His deepest wish was to bring joy into as many lives as possible. We ask for support during this time to allow our family to grieve in privacy. And we wish for all of those to whom Julian brought joy, to continue to find joy in life. We are grateful for the memories.”

McMahon was the son of Sir William McMahon, who served as Australia’s prime minister from 1971 to 1972. He began his career as a model before transitioning to acting on Australian television.

McMahon broke into American television with roles in NBC’s soap opera “Another World,” the crime drama “Profiler” and as the demonic Cole Turner on “Charmed.” His big break came with the FX medical drama “Nip/Tuck,” where he played the plastic surgeon Dr. Christian Troy for six seasons. The role earned him a Golden Globe nomination.

In film, McMahon was best known for playing the metallic villain Dr. Doom in “Fantastic Four” (2005) and its sequel “Fantastic Four: Rise of the Silver Surfer” (2007). His other film credits include “Premonition,” “RED” and “Paranoia.”

Most recently, McMahon starred as FBI agent Jess LaCroix in CBS’s “FBI: Most Wanted” for three seasons before leaving the series in March 2022. He also appeared in Hulu’s “Marvel’s Runaways” and appeared in Netflix’s series “The Residence,” where he played the Australian prime minister.
