Hammer’s breakthrough horror feature predated its Famous Monsters movies and was also a universe-building property; this remake of Nigel Kneale’s BBC-TV sci-fi serial would be followed by more TV and movie installments. Brian Donlevy stars as the titular professor, whose rocket expedition boomerangs back to Earth with its sole surviving astronaut now incubating something alien. With Thora Hird, Gordon Jackson, LioneI Jeffries, and (at age nine) Jane Asher.
