This is the second DOCTOR WHO theatrical film starring Peter Cushing. The oddest part is that the character he plays is never mentioned whatsoever! Nor, in fact, are the Daleks mentioned by name! Even when the narrator mentions the title of the film, he skips that part!
As a point of trivia, though, the most interesting thing about this film, based closely on an early BBC William Hartnell serial of the Doctor, is the appearance of Bernard Cribbens who, four decades later, returned to the franchise as Donna Noble's grandfather!
