Patrick Muldoon, known for his roles in Days of Our Lives and Melrose Place, has died at the age of 57.
The actor and producer suffered a heart attack at the Beverly Hills home he shared with his girlfriend Miriam Rothbart on Sunday morning, his manager confirmed to Variety.
Muldoon started his acting career while still in college at the University of Southern California with a two-episode arc on the sitcom Who’s the Boss?
Shortly after his 1991 graduation, he landed a three-episode recurring role on popular teen comedy Saved By The Bell.
His breakthrough role came when he landed the part of boxer Austin Reed on Days of Our Lives, appearing from 1992 to 1995 and later returning from 2011 to 2012.
He is also known for playing villain Richard Hart in Melrose Place from seasons three to five and on the big screen, for his role as Zander Barcalow in the 1997 sci-fi movie Starship Troopers, alongside his ex-girlfriend Denise Richards.
He reunited with Richards to film his latest acting role in a crime thriller titled Dirty Hands, which is slated to be released later this year.
Richards and the actor had remained close friends after dating on and off for five years during the 1990s.
He appeared on an epsiode of The Real Housewives of Beverly Hills when Richards was a cast member as well as on her reality show, Denise Richards & Her Wild Things, to film a music video together.
He followed his passion for music and was the lead singer and guitarist for the rock band, The Sleeping Masses.
Muldoon also worked as a producer, earning an executive producer credit in many films including The Tribes of Palos Verdes, Arkansas, Marlowe, The Dreadful,, and most recently Kockroach, which is currently filming and stars Chris Hemsworth and Taron Egerton.
In his last Instagram post a day before his death, he wrote: ‘So excited to be a part of this amazing project KOCKROACH directed by Matt Ross starring Chris Hemsworth, Taron Edgerton, Zazie Beetz And Alec Baldwin. Filming now in Australia.’
Fans flooded the post with tributes, with one writing: ‘Grew up watching you in starship troopers . R.I.P legend.’
Patrick made a public appearance at the 2026 Saturn Awards in March.
Last year the actor teased a possible return to Days of Our Lives, appearing in a video shared on Peacock’s official Instagram page.
In the brief clip, he could be seen wandering around the set of the daytime show before telling the cameras: ‘Oh my God I’m in Salem! It’s good to be back’.
