Button - Im Sumpf der Atommafia

This taut, underrated little thriller might be called a British version of "The Parallax View". Ian Bannen plays a Profumo-like MP targeted by the security services because he knows too much. His career is ruined by muck-raking reporter Gabriel Byrne but the latter's determination to get to the bottom of the story, and his guilt at the death of a colleague (the superb Denholm Elliott), lead him down unexpected political byways...

"Defence of the Realm" can boast excellent location work and a convincing recreation of the vanished world of the "old" hard-drinking Fleet Street. The tone becomes darker and more claustrophobic as the film goes on and the apolitical Byrne enters a paranoid world of car headlights in the rearview mirror, bugged telephones and rifled apartments. The film taps into many of the issues that concerned the British Left in the mid-eighties (secrecy, American missiles on UK soil, the unaccountability of the security services, newspaper obsession with sexual gossip to the exclusion of harder material) and builds to a clever, if shocking, double-twist climax. Well worth locating and viewing.
