It terrified the audience on its first transmission in 1968, not surprising as its author was M. R. James, was the master of ghost stories, who re-invented the genre with his tales of the supernatural. Whistle and I’ll Come to You starred Michael Hordern, and was produced and directed by Jonathan Miller, the former star, along with Peter Cook, Dudley Moore and Alan Bennett, of Beyond the Fringe. Miller had already made his mark directing The Drinking Party, The Death of Socrates and Alice in Wonderland for the BBC before making this classic chiller, one described as:

“A masterpiece of economical horror that remains every bit as chilling as the day it was first broadcast.”
