The director and actor told Entertainment Weekly that it was “crazy” that his mother played a woman with cognitive decline in the iconic romance — and now she’s struggling with the progressive disease herself. "I got my mom to play older Allie, and we spent a lot of time talking about Alzheimer's and wanting to be authentic with it, and now, for the last five years, she's had Alzheimer's," Cassavetes told EW about his mother, now 93, who played the older version of Rachael McAdams’ character in the film.

Kevin Winter/Getty “This last one — The Notebook, based on the novel by Nicholas Sparks — was particularly hard because I play a character who has Alzheimer's. I went through that with my mother, and if Nick hadn't directed the film, I don't think I would have gone for it,” she told O magazine in 2004.

"It seems to have worked," he said, "and I'm very proud of it."
