The 90-minute drama will tell the full story of Hitchcock’s obsessive relationship with The Birds actress Tippi Hedren, who will played by Sienna Miller.

The cast also includes Imelda Staunton (Harry Potter) as Alma Hitchcock and Penelope Wilton (Downton Abbey) as Hitchcock’s loyal assistant, Peggy Robertson.

Writer Gwyneth Hughes (The Mystery Of Edwin Drood, Five Days) commented: “It’s been the most enormous privilege to talk at length to Tippi Hedren, the last “Hitchcock blonde” in the life of Britain’s most original and successful film director. At the time, in the early 1960s, the American star suffered in silence. But now, at the age of 81, her wisdom and insights have helped me to put her real life ordeal on to the screen.

She continued: “I know Tippi is absolutely thrilled, as I am, with the casting of Sienna Miller to play her, and when the two of them met recently they got on like a house on fire. I’ve loved Toby Jones’ work for years and for me, he is the perfect choice to play the tormented genius, Alfred Hitchcock.”
