Catherine O'Hara's co-star Michael Keaton is paying his respects. Michael and Catherine both starred in Beetlejuice and reunited for the sequel Beetlejuice Beetlejuice in 2024, and they also worked on other projects together. After news of the 71-year-old's death on Friday, the actor was quick to share a tribute to their friendship. Sharing a recent photo of them, he wrote on Instagram: "We go back before the first Beetlejuice. She's been my pretend wife, my pretend nemesis and my real life, true friend. This one hurts. Man am I gonna miss her. Thinking about Beau as well." Very sweet.
