Fans of the holiday classic Home Alone are mourning today alongside the cast as Devin Ratray, known for his role as the abrasive older brother Buzz McCallister, shared a deeply emotional tribute to his on-screen mother, Catherine O’Hara. The news of O’Hara’s passing has sent shockwaves through the entertainment industry, leaving those who worked closely with her struggling to find the words to describe the loss.

Ratray took to social media to express the profound sense of grief he is feeling, describing O’Hara not just as a colleague, but as a monumental figure in his life. He noted that she was one of the greatest people he ever had the privilege of meeting. The actor admitted to being in a state of shock, stating that the reality of the situation simply hasn’t registered yet, leaving him feeling completely bewildered and numb.

The bond between the McCallister family cast members has remained a point of nostalgia for fans for over three decades. O’Hara’s portrayal of Kate McCallister—the fierce, determined mother who would do anything to get back to her son Kevin—is considered one of the most heart-wrenching and iconic performances in cinema history. Ratray’s grief reflects the sentiment of a generation of viewers who saw O’Hara as the ultimate “movie mom.”

While the world remembers her for her legendary roles in Schitt’s Creek, Beetlejuice, and her ground-breaking work in sketch comedy with SCTV, those who shared the screen with her during the 1990 film remember a kind, brilliant, and irreplaceable soul who brought warmth to every set she stepped on.
