Catherine O'Hara and Macaulay Culkin were more than just costars. They were family.

Culkin, who played O'Hara's son in the 1990 Christmas comedy "Home Alone," paid tribute to the Emmy-winning actress in an emotional Instagram post following O'Hara's death on Friday, Jan. 30.

O'Hara's manager confirmed her death to People magazine, while Variety and Deadline reported that O'Hara died at home after "a brief illness," citing her agency CAA.

"Mama. I thought we had time. I wanted more," Culkin wrote in the post, which featured a then-and-now-style collage of Culkin and O'Hara. "I wanted to sit in a chair next to you. I heard you. But I had so much more to say. I love you. I'll see you later."

A veteran in the entertainment industry, O'Hara has been one of the most lauded and respected actors of her generation, winner of two career Emmy Awards, a Golden Globe and two Actor Awards (formerly Screen Actors Guild Awards). She was nominated for two Emmys at the 2025 ceremony.
