Horror Express (Pánico en el Transiberiano in Spain and also known as Panic on the Trans-Siberian Express), is a 1972 Spanish-British science fiction-horror film, produced by Bernard Gordon and Gregorio Sacristan, directed by Eugenio Martín, that stars Christopher Lee, Peter Cushing, Alberto de Mendoza, Silvia Tortosa, and Telly Savalas. The screenplay was written by Arnaud d’Usseau and Julian Zimet (credited as Julian Halevy).
In 1906, Saxton (Lee), a renowned British anthropologist, is returning to Europe by the Trans-Siberian Express from China to Moscow. With him is a crate containing the frozen remains of a primitive humanoid creature that he discovered in a cave in Manchuria. He hopes it is a missing link in human evolution. Doctor Wells (Peter Cushing), Saxton’s friendly rival and Royal Geological Society colleague, is also on board but travelling separately. Before the train departs Shanghai, a thief is found dead on the platform. His eyes are completely white, without irises or pupils, and a bystander initially mistakes him for a blind man.
