See Dermot Mulroney’s Career in Pictures: 40 Years of Heartthrob Moments (Photos)
Dermot Mulroney was just 24 years old when he caught our eye in 1988’s Young Guns, but the gifted classically trained cellist started out ever earlier; he first got his start in TV with 1986’s Fame and made-for-TV Sin of Innocence. Since then, the now 61-year-old star has carved out a delightful and diverse path through Hollywood, bringing charm, heart and some rugged cool (and occasional horror) to the big screen for over three decades.
He made his mark with heartfelt dramas like Must Love Dogs and indie gems such as Longtime Companion. But it was his irresistible turn as the groom in the rom-com classic My Best Friend’s Wedding opposite Julia Roberts that truly won audiences over.
Whether he’s playing a swoon-worthy love interest, a tough-as-nails cowboy, or popping up unexpectedly in quirky comedies and creepy thrillers, along with hit TV shows from Friends and New Girl to his current run on Chicago Fire as Dom Pascal, Mulroney’s presence is always a welcome one.
On June 21, Mulroney filed for divorce from his wife of 15 years, Prima Apollinaare, citing irreconcilable differences. He asked for joint custody of their daughters, Mabel Ray, 17, and Sally June, 15. Mulroney met Apollinaare (who changed her name from Tharita Cutulle, according to People) a year after his divorce from actress Catherine Keener.
Here’s a look at some of Mulroney’s roles in TV and film over the years.
