Hollywood is mourning the loss of Catherine O’Hara, who died at age 71 following a brief illness, according to her representatives. Best known to generations as Kate McCallister, the devoted mother in the Home Alone films, O’Hara’s passing prompted an outpouring of tributes across the entertainment world. Among the most personal came from Macaulay Culkin, who played her on-screen son. Sharing photos from their time together and later reunions, Culkin referred to her simply as “Mama,” writing, “I thought we had time,” a message that reflected both grief and deep affection.
Their bond, formed when Culkin was a child star and O’Hara an established performer, endured long after filming ended. O’Hara’s portrayal of Kate McCallister became the emotional anchor of Home Alone, grounding its comedy with warmth and sincerity. Culkin has often credited her with providing stability and kindness during an intensely public childhood. That connection was on full display in December 2023, when O’Hara joined him at his Hollywood Walk of Fame ceremony, delivering a heartfelt and playful speech that moved him to tears.
