Just as Mercury continues its retrograde antics, reminding us that life’s details can surprise us when least expected, news has just emerged clarifying the final curtain for comedy legend Catherine O’Hara. The beloved star of Home Alone, whose on-screen antics brought joy to millions, passed away at 71 — and now we know it was a blood clot in her lungs, with rectal cancer lurking in the background like a plot twist nobody wanted. It’s a sobering reminder that even stars align unpredictably — and that behind her infectious humor was a fierce battle most never saw coming. As the universe shifts overhead, we remember a true icon whose laughter still echoes through the constellations of film and TV. LEARN MORE.

Catherine O’Hara’s cause of death has been confirmed as a blood clot in the lungs.
The Home Alone star died on 30 January at the age of 71. At the time, her management said she had passed away at her Los Angeles home ‘following a brief illness’.
More details have now been released as TMZ obtained the death certificate published by Los Angeles County Medical Examiner’s Office. It listed pulmonary embolism as the immediate cause of death (this is when a blood clot blocks a blood vessel in the lungs) and rectal cancer as the underlying cause.
The Canadian’s incredible career spanned five decades, becoming an absolute icon of the screen. Her legendary list of credits of course included the Christmas classic Home Alone films as well as the likes of Schitt’s Creek, Beetlejuice and the sketch comedy series where she made her name – Second City Television.

And tributes flooded in globally for O’Hara, with her on-screen son, Macaulay Culkin, writing: “Mama. I thought we had time.
“I wanted more. 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.”
LADbible Group has contacted the Los Angeles County Medical Examiner’s Office and O’Hara’s former representatives for comment.
