Thrills, spills, action and adventure in this roller coaster of a movie…only joking! I’m being facetious of course as we believe they show the first half of this film in sleep research centres for the control group. But seriously, it’s one to make you think as Gene Hackman slithers about recording the conversations of a couple he realises (eventually!) are to be murdered. It gets going further in and becomes really quite good, but if you’re up around when this is usually screened save on hot milk and heating and watch this instead.
