The abominable Dr Terror introduces a brace of frighteners starring several actors regarded as being among the doyens of the genre.

Horror Express
Starring Christopher Lee, Peter Cushing, Telly Savalas
In the early 1900s, an English anthropologist discovers a strange, frozen ape-man in China. On board the Trans-Siberian Express, he encounters an old rival, determined to find out about his discovery. Meanwhile, the creature defrosts and escapes from its crate - revealing itself to be an alien sent during prehistory on a mission to claim the earth. It is able to force living creatures to absorb it into their bodies where it deprives them of their intellectual faculties, turning them into zombies in the process. So begins a journey of terror for all the passengers when the creature wants to learn how to make a spaceship to transport it home.
