Christian Cousins, the former child actor who starred alongside Arnold Schwarzenegger in “Kindergarten Cop,” has died at 43, his half-brother confirmed in an emotional Instagram tribute last month.
Jonas Roeser, 35, broke the news on the platform in October, revealing that Cousins had been battling liver disease before his passing. The brothers shared a biological father but were raised in different states, with Roeser growing up in Washington while Christian and his identical twin Joseph “Joey” Cousins spent their childhood in California.
Roeser explained that he first connected with the twins when he reached college age, long after he had already watched them on screen. “Before that, I grew up watching them on television in ‘Knots Landing’ and the lead role of Dominic in ‘Kindergarten Cop’ with Arnold Schwarzenegger,” he wrote on Instagram.
The twins’ early acting careers made them familiar faces to 1980s and 1990s television audiences. Joey and Christian Cousins shared roles and appeared together in the long-running CBS prime-time soap “Knots Landing,” which ran from 1979 to 1993. Christian later landed the part of Dominic, the young student who famously tells Schwarzenegger’s detective character that boys have a penis and girls have a vagina, in the 1990 comedy hit.
Despite those high-profile credits, Roeser emphasized that his brother’s Hollywood work represented only a fraction of who he was. “But those roles are only a small part of how I’ll remember Christian,” he wrote. “He was a character, full of passion and energy, with big stories and even bigger dreams.”
Roeser noted that his half-brother “had been very sick” in the period leading up to his death. The liver disease that ultimately claimed Cousins’s life had left him in considerable pain, according to the tribute.
The grieving brother found solace in faith as he processed the loss. “It brings me comfort to believe he is now in heaven with his mother, free from the pain he was carrying,” Roeser shared on Instagram.
He directed his final words in the post directly to the sibling he had known for roughly two decades. “Rest easy, Christian. I hope your soul is at rest and that you’ve found peace,” Roeser wrote. “You are my brother and you will be missed.”
The Cousins twins stepped back from acting as they grew older. While Joey maintained a lower public profile in adulthood, Christian’s health struggles remained largely private until his brother’s announcement. The liver disease that caused his death had not been previously reported in entertainment news coverage.
Schwarzenegger’s comedy, directed by Ivan Reitman, became a fixture of 1990s cable television and home video after its theatrical release. The film followed an undercover detective posing as a kindergarten teacher to catch a drug dealer, with Dominic serving as one of his most memorable students. The movie grossed over $200 million worldwide against a $26 million budget.
“Knots Landing,” the “Dallas” spin-off where the twins appeared, ranked among the era’s most successful nighttime soaps and launched or sustained multiple careers during its fourteen-season run.
Roeser has not posted additional public statements about memorial arrangements or family gatherings since his October tribute.
