Justin Trudeau has paid a glowing tribute to Catherine O'Hara

Alongside a throwback photo of them together, Trudeau wrote on X: "From SCTV to Home Alone to her unforgettable role as Moira Rose on Schitt's Creek, Catherine O'Hara was a beloved Canadian icon with a rare gift for comedy and heart. She made people laugh across generations and helped bring Canadian storytelling to the world in a way only she could.

"My thoughts are with her family, friends, and everyone who found joy in her work. (sic)"

Meanwhile, Seth Rogen previously hailed the actress as a huge influence on his own career.

The film star took to social media to pay a heartfelt tribute to O'Hara, his former co-star on The Studio.

Seth - who has enjoyed huge success with movies like Superbad, Knocked Up, and Pineapple Express - wrote on Instagram: "Really don't know what to say... I told O'Hara when I first met her I thought she was the funniest person I'd ever had the pleasure of watching on screen. Home Alone was the movie that made me want to make movies. Getting to work with her was a true honour. She was hysterical, kind, intuitive, generous... she made me want to make our show good enough to be worthy of her presence in it. This is just devastating. We're all lucky we got to live in a world with her in it. (sic)"

Judd Apatow also paid tribute to the late actress, describing her as a "really special person".

The 58-year-old filmmaker wrote in response: "[heart emoji] brilliant and kind. Riotously funny for fifty years. A really special person. (sic)"
