It's a shame that this didn't do too well at the box office. It's what might have been for Cushing and Lee in their best pairing (storywise) of the seventies. The film sticks fairly closely to the exciting and innovative novel by the great John Blackburn. If this film had done better box office, we might have seen a screen version of 'Bury Him Darkly' another horror/sci-fi/ancient evil cocktail and the best of Blackburn's output. Now that there is only Hollywood knocking out films, best lost forever than have them ruin that. Peter Sasdy is the Director who must be drawn to 'ancient evil' mixed with sci-fi stories, because the previous year he directed Nigel Kneale's 'The Stone Tape' and a big screen version of 'Doomwatch'. Nothing But The Night has a flavour of the Wicker Man about it, without the futility and the isolation. There's a stalwart crew of British actors backing up the two main protagonists like Keith Barron, Fulton Mackay and completing the Kneale link, ex-Quatermass, John Robinson. If you like to see Cushing and Lee both playing the good guys for a change, this is the film for you.
