A decade after the shocking death of Hollywood star John F. Donovan, a young actor reflects on the private correspondence that once linked their lives. Directed by Xavier Dolan, this introspective drama shifts between two timelines, following the meteoric rise and suffocating fame of Donovan, played by Kit Harington, and the adolescence of his biggest fan, Rupert Turner, portrayed by Jacob Tremblay. As a child, Rupert found solace and guidance in the secret letters exchanged with his idol, a relationship hidden from the public and Donovan's formidable manager, played by Kathy Bates, and scrutinized by a relentless journalist, Thandie Newton. The film weaves a poignant tapestry of memory and myth, exploring the profound impact of this clandestine friendship on both a man trapped by his public image and a boy searching for his place in the world. With a stellar cast including Natalie Portman and Susan Sarandon, it paints a melancholic portrait of celebrity, connection, and the stories we leave behind.
