The Romantic Englishwoman (1975)

Synopsis
Tom Stoppard and Thomas Wiseman's intricate script for The Romantic Englishwoman credibly explores the notion that a writer can manipulate the people in his life as deftly as he can manipulate the characters in his imagination. The title character Elizabeth, played by Glenda Jackson, is the wife of Lewis (Michael Caine), a novelist. At this point in his life, Lewis thinks in nothing but literary terms: Elizabeth is vacationing in Europe alone, ergo she must be having an affair. Half out of frustration, she confirms her husband's suspicions by romancing German drug dealer Thomas (Helmut Berger). Things get even dicier when Lewis invites Thomas into his home, requesting his technical advice on a screenplay he is working on. ~ Hal Erickson, All Movie Guide
