Actor Patrick Muldoon has died at age 57.
The Days of Our Lives and Starship Troopers actor died following a heart attack early Sunday, April 19, Deadline reported on Monday, April 20. The actor’s manager subsequently confirmed his death to Variety.
Us Weekly has reached out to Muldoon’s representatives for comment.
Friends of the star described him to Deadline as “endlessly generous — with his poetry, his humor, and his unmistakable presence,” adding that Muldoon “loved animals and people alike, gave unforgettable hugs, and possessed a rare quality of making others feel safe and seen.”
The statement added, “Stylish, charismatic, and full of life, he embraced each day with a full-tilt, rock ’n’ roll spirit.”
Elisabeth Costa de Beauregard Segel, president of global sales and distribution at Muldoon’s company, Storyboard Media, told Us, “Heaven got another angel far too soon,” calling Muldoon “the most amazing person.”
Muldoon first broke out in the early 1990s with stints on sitcoms Who’s the Boss? and Saved by the Bell. In 1992, he joined daytime soap Days of Our Lives as Austin Reed before exiting the show in 1995. He briefly reprised his role from 2011 to 2012, when he was among a handful of cast members let go. He also had a recurring role as villain Richard Hart on primetime soap Melrose Place between 1995 and 1996.
In 1997, Muldoon appeared alongside ex-girlfriend Denise Richards and Casper Van Dien in Starship Troopers. He recently reunited with Richards, 55, for his “Gray Again” music video, in which the actress starred. The making of the romantic video was documented on a 2025 episode of Richards’ short-lived Bravo reality series, Denise Richards & Her Wild Things.
During the episode, Richards revealed that she fell out of touch with Muldoon while she was married to ex-husband Charlie Sheen.
“I did not speak to Pat when I was married to Charlie. And it was hard, because I didn’t want to lose him as a friend friend. But, towards the end of the marriage, I talked to him all the time about him,” she said.
“Mine and Pat’s relationship romantically was years ago, and it’s just a deep friendship. I’m so grateful Aaron respects that because Charlie… he had a hard time with my relationship with Pat,” she continued, referring to her estranged husband Aaron Phypers, from whom she filed for divorce in July 2025.
In a confessional, Phypers said he did not “get jealous like that” seeing Richards and Muldoon kiss for Muldoon’s “Gray Again” music video, adding, “Patrick and I, we have a very good relationship.”
According to Deadline, Muldoon’s latest film, Dirty Hands, is set for release later this year.
Muldoon was also an accomplished film producer through Storyboard Media. Deadline reported that at the time of his death he was executive producer on the movie Kockroach, which recently began filming and stars Chris Hemsworth and Taron Egerton.
