Night Caller from Outer Space

Night Caller from Outer Space, also known as simply The Night Caller or Blood Beast from Outer Space, is a British 1965 science fiction film directed by John Gilling. It is based on Frank Crisps novel The Night Callers.

Leonard Maltin called it a welldone scifi thriller and rated it as two and a half stars. Author Steve Puchalski said, this alleged film is dry and slow paced, uninvolving and uninspiring. UK prints of the film feature Alan Havens version of the hit instrumental Image as its theme.
